Abstract

The first evidence for β-delayed proton emission from the 16+ spin gap isomer in 96Cd is presented. The data were obtained from the Rare Isotope Beam Factory, at the RIKEN Nishina Center, using the BigRIPS spectrometer and the EURICA decay station. βp branching ratios for the ground state and 16+ isomer have been extracted along with more precise lifetimes for these states and the lifetime for the ground state decay of 95Cd. Large scale shell model (LSSM) calculations have been performed and WKB estimates made for ℓ=0,2,4 proton emission from three resonance-like states in 96Ag, that are populated by the β decay of the isomer, and the results compared to the new data. The calculations suggest that ℓ=2 proton emission from the resonance states, which reside ∼5 MeV above the proton separation energy, dominates the proton decay. The results highlight the importance of core-excited wavefunction components for the 16+ state.

Abstract

Wannier90 is an open-source computer program for calculating maximally-localised Wannier functions (MLWFs) from a set of Bloch states. It is interfaced to many widely used electronic-structure codes thanks to its independence from the basis sets representing these Bloch states. In the past few years the development of Wannier90 has transitioned to a community-driven model; this has resulted in a number of new developments that have been recently released in Wannier90 v3.0. In this article we describe these new functionalities, that include the implementation of new features for wannierisation and disentanglement (symmetry-adapted Wannier functions, selectively-localised Wannier functions, selected columns of the density matrix) and the ability to calculate new properties (shift currents and Berry-curvature dipole, and a new interface to many-body perturbation theory); performance improvements, including parallelisation of the core code; enhancements in functionality (support for spinor-valued Wannier functions, more accurate methods to interpolate quantities in the Brillouin zone); improved usability (improved plotting routines, integration with high-throughput automation frameworks), as well as the implementation of modern software engineering practices (unit testing, continuous integration, and automatic source-code documentation). These new features, capabilities, and code development model aim to further sustain and expand the community uptake and range of applicability, that nowadays spans complex and accurate dielectric, electronic, magnetic, optical, topological and transport properties of materials., Comment: 26 pages, 8 figures

6. Magnetoelectric multipoles in metals

Subjects
Condensed Matter - Materials Science
Abstract

We demonstrate computationally the existence of magnetoelectric multipoles, arising from the second order term in the multipole expansion of a magnetization density in a magnetic field, in noncentrosymmetric magnetic metals. While magnetoelectric multipoles have long been discussed in the context of the magnetoelectric effect in noncentrosymmetric magnetic insulators, they have not previosuly been identified in metallic systems, in which the mobile carriers screen any electrical polarization. Using first-principles density functional calculations we explore three specific systems: First, a conventional centrosymmetric magnetic metal, Fe, in which we break inversion symmetry by introducing a surface, which both generates magnetoelectric monopoles and allows a perpendicular magnetoelectric response. Next, the hypothetical cation-ordered perovskite, SrCaRu$_2$O$_6$, in which we study the interplay between the magnitude of the polar symmetry breaking and that of the magnetic dipoles and multipoles, finding that both scale proportionally to the structural distortion. Finally, we identify a hidden antiferromultipolar order in the noncentrosymmetric, antiferromagnetic metal Ca$_3$Ru$_2$O$_7$, and show that, while its competing magnetic phases have similar magnetic dipolar structures, their magnetoelectric multipolar structures are distinctly different, reflecting the strong differences in transport properties., Comment: 13 pages, 6 figures

Abstract

The lifetimes of the $2^+_1$, the $2^+_2$ and the $3^-_1$ states of $^{210}$Po have been measured in the $^{208}$Pb($^{12}$C,$^{10}$Be)$^{210}$Po transfer reaction by the Doppler-shift attenuation method. The results for the lifetime of the $2^+_1$ state is about three times shorter than the adopted value. However, the new value still does not allow for consistent description of the properties of the yrast $2^+_1$, $4^+_1$, $6^+_1$, and $8^+_1$ states of $^{210}$Po in the framework of nuclear shell models. The Quasi-particle Phonon Model (QPM) calculations also cannot overcome this problem thus indicating the existence of a peculiarity which is neglected in both theoretical approaches.

8. Quantifying the structural integrity of nanorod arrays

Subjects

Abstract

Arrays of aligned nanorods oriented perpendicular to a support, which are accessible by top-down lithography or by means of shape-defining hard templates, have received increasing interest as sensor components, components for nanophotonics and nanoelectronics, substrates for tissue engineering, sur-faces having specific adhesive or antiadhesive properties and as surfaces with customized wettability. Agglomeration of the nanorods deteriorates the performance of components based on nanorod arrays. A comprehensive body of literature deals with mechanical failure mechanisms of nanorods and design criteria for mechanically stable nanorod arrays. However, the structural integrity of nanorod arrays is commonly evaluated only visually and qualitatively. We use real-space analysis of microscopic images to quantify the fraction of condensed nanorods in nanorod arrays. We suggest the number of array elements apparent in the micrographs divided by the number of array elements a defect-free array would contain in the same area, referred to as integrity fraction, as a measure of structural array integrity. Reproducible procedures to determine the imaged number of array elements are introduced. Thus, quantitative comparisons of different nanorod arrays, or of one nanorod array at different stages of its use, are possible. Structural integrities of identical nanorod arrays differing only in the length of the nanorods are exemplarily analyzed.

9. First-principles calculation of the bulk magnetoelectric monopolization: Berry phase and Wannier function approaches

Author

Subjects
Condensed Matter - Materials Science
Abstract

We present a formalism to calculate the macroscopic magnetoelectric monopolization from first principles within the density functional theory framework. An expression for the monopolization in the case of insulating collinear magnetism is derived first in terms of spin-polarized Wannier functions then recast as a Berry phase. We propose an extension to the general, non-collinear case which we implement computationally in the Wannier function form and use to calculate the magnetoelectric monopolizations of LiMnPO$_4$ and Cr$_2$O$_3$. We find that, while the former is well approximated by a summation over the formal local spin moments, the latter shows significant deviations from this approximation. We suggest that equating the Berry phase value with a sum over local moments provides an unambiguous route to defining the size of the local magnetic moment in magnetoelectric antiferromagnets containing only one type of magnetic ion., Comment: 8 pages, 1 figure

Abstract

The electromagnetic structure of $^{140}$Sm was studied in a low-energy Coulomb excitation experiment with a radioactive ion beam from the REX-ISOLDE facility at CERN. The $2^+$ and $4^+$ states of the ground-state band and a second $2^+$ state were populated by multi-step excitation. The analysis of the differential Coulomb excitation cross sections yielded reduced transition probabilities between all observed states and the spectroscopic quadrupole moment for the $2_1^+$ state. The experimental results are compared to large-scale shell model calculations and beyond-mean-field calculations based on the Gogny D1S interaction with a five-dimensional collective Hamiltonian formalism. Simpler geometric and algebraic models are also employed to interpret the experimental data. The results indicate that $^{140}$Sm shows considerable $\gamma$ softness, but in contrast to earlier speculation no signs of shape coexistence at low excitation energy. This work sheds more light on the onset of deformation and collectivity in this mass region., Comment: 15 pages, 12 figures

12. Modellierung des tieferen Untergrundes des Norddeutschen Beckens: Das Projekt TUNB – von der Idee zur Umsetzung

Author

von Goerne, Gabriela, Jähne-Klingberg, Fabian, Steuer, Stephan, and Thöle, Hauke

Abstract

Based on existing map series of the North German Basin and their partial implementation into 3D models, a harmonized 3D-model of the North German Basin was developed in the project TUNB from 2014 onwards. The modelling work was conducted by the State Geological Surveys (SGD) of Schleswig-Holstein, Mecklenburg-Vorpommern, Brandenburg, Saxony-Anhalt, and Lower Saxony, as well as the Federal Institute for Geosciences and Natural Resources (BGR). The areas of the city-states of Hamburg, Bremen, and Berlin were modelled by the SGD of the neighbouring states. The German Exclusive Economic Zone (EEZ) of the North Sea, as well as parts of the Baltic Sea, were modelled by the BGR. After determination on the horizons to be modelled and the harmonization measures to be used by all parties, an initial test was run in a pilot region. Following this successful test, the entire model was created by the respective SGD and the BGR. The individual state models were handed over to the BGR, compiled there, and made available through a 3D web viewer application. In total, the model comprises 15 horizons, 5331 faults and 270 salt structures. It covers an area of approximately 167,500 km2, making it one of the largest 3D models in the world.

Subjects

Abstract

We introduce a mechanism in which coupling between fluctuating spin magnetic dipole moments and polar optical phonons leads to a non-zero ferroic ordering of quasi-static magnetoelectric multipoles. Using first-principles calculations within the LSDA$+U$ method of density functional theory, we calculate the magnitude of the effect for the prototypical cuprate superconductor, HgBa$_2$CuO$_4$. We show that our proposed mechanism is consistent, to our knowledge, with all experimental data for the onset of the pseudo-gap phase and therefore propose the quasi-static magnetoelectric multipole as a possible pseudo-gap order parameter. Finally, we show that our mechanism embraces some key aspects of previous theoretical models, in particular the description of the pseudo-gap phase in terms of orbital currents., Comment: 11 pages, 6 figures

18. Generation of de novo reference values for the thyroid hormones TT4, fT4 and TSH in healthy pet rabbits (Oryctolagus cuniculus) and healthy pet guinea pigs (Cavia porcellus) in conjunction with a TRH-stimulation test.

Abstract

In rabbits and guinea pigs, total thyroxine (TT4) and free thyroxine (fT4) reference values have been previously published. However, most studies have been performed on laboratory animals with small sample sizes. A reference value for thyroid-stimulating hormone (TSH) measurement has not yet been established for either species. With the increasing popularity of pet guinea pigs and rabbits in veterinary practice, established reference values are needed to make a diagnosis and promptly initiate appropriate treatment. Plasma samples from a healthy and defined animal population of 41 pet rabbits (n = 41 TT4, fT4, TSH) and 73 pet guinea pigs (n = 73 TT4 and fT4; n = 51 TSH) were evaluated using chemiluminescence assay (CLIA; for TT4, fT4) and enzyme-linked immunosorbent assay (ELISA; for TSH) to establish reference values. A thyrotropin teleasing hormone (TRH)-stimulation test (n = 4; for each species) was conducted to validate the TSH ELISA test kits. Range, mean, median, standard deviation, interquartile range, 95% reference interval, and 90% confidence intervals for lower and upper reference limits of TT4, fT4, and TSH in healthy pet guinea pigs and healthy pet rabbits were assessed. In addition, the influence of age, sex, and housing on TT4, fT4, and TSH levels was investigated. In this study, TSH reference values were established in pet rabbits and guinea pigs for the first time. Reference values for both TT4 and fT4 were also established de novo for both species. Only with evidence- and population-based reference values can thyroid diseases be precisely and correctly diagnosed to prevent inadequate treatment. [ABSTRACT FROM AUTHOR]

Abstract

A systematic study was performed of microsecond γ-decaying isomers around Sn100 produced in a fragmentation reaction of a Xe124 beam at 345 MeV/u at the Radioactive Ion Beam Factory of the RIKEN Nishina Center in Saitama, Japan. Half-lives of isomeric states in that region were remeasured allowing us to improve the currently available experimental information. Reduced transition probabilities were deduced and compared to shell-model calculations in various model spaces. The recently reported low-energy transitions in Rh92 and Ag96 were remeasured with improved precision. Additionally, experimental information on isomeric ratios, including five new ones, were extracted and compared to a previous experimental study and the sharp cutoff model of fragmentation reaction.

Abstract

• Mapping of CO 2 storage sites in the Buntsandstein subgroup in the exclusive economic zone of the German North Sea. • Static CO 2 storage capacity estimation via Monte Carlo simulations. • Evaluation of individual storage sites in terms of structural complexity and compartmentalisation. The storage of CO 2 in deeply buried geological formations provides a contribution to mitigate hard-to-abate CO 2 emissions from industry. Robust geological models and capacity estimations are crucial for the successful planning and implementation of safe storage projects. This study focuses on the CO 2 storage potential of the Middle Buntsandstein Subgroup within the Exclusive Economic Zone of the German North Sea. We have mapped a total of 71 potential storage sites based on existing 3D models, seismic and well data. Static CO 2 capacities are calculated for each structure using Monte Carlo simulations with 10,000 iterations to account for uncertainties. All potential reservoirs are evaluated based on their potential capacity, burial depth, top seal integrity and trap type. We have identified 38 potential storage sites with burial depths between 800 m and 4500 m, reservoir capacities (P50) above 5 Mt CO 2 and suitable sealing units. The estimated cumulative static storage capacity percentiles of these structures range between P10 = 902.08 Mt and P90 = 5508.93 Mt, with P50 = 2554.10 Mt. We expect the best storage conditions on the West Schleswig Block, where salt-controlled anticlines with moderate burial depths, large reservoir capacities and limited lateral flow barriers are the dominant trap types. Relatively poor storage conditions can be expected for small (P50 < 5 Mt CO 2), deeply buried (> 4500 m) and structurally complex potential storage sites in the Horn and Central Graben. Our study highlights the most prolific reservoirs and discusses the most suitable locations for further exploration. [ABSTRACT FROM AUTHOR]

7 pags., 4 figs. -- Presented at the Zakopane Conference on Nuclear Physics “Extremes of the Nuclear Landscape”, Zakopane, Poland, August 26–September 2, 2018. -- Open Access funded by Creative Commons Atribution Licence 4.0, The study of nuclei in the region around the N = Z doubly-magic nucleus 100Sn has been of long standing interest for the nuclear structure and nuclear astrophysics. Recently, Park et al. have reported on properties of γ-decaying isomers and isomeric ratios in the vicinity of 100Sn. That experiment was performed at the Radioactive Ion Beam Factory (RIBF) of the RIKEN Nishina Center in Japan as a part of the EURICA campaign. Neutron-deficient nuclei were produced in a fragmentation reaction of a 124Xe primary beam on a 9Be target at an energy of 345 MeV/A. Secondary ions were separated and identified in the BigRIPS fragment separator and implanted in the silicon detector array WAS3ABi. The data presented here were obtained in another experiment performed at the RIBF using the same reaction but slightly different separator settings. New results of ratios of isomeric population and half-lives of γ-decaying isomers populated in the experiment are presented., This work was carried out at the RIBF operated by the RIKEN Nishina Center, RIKEN and CNS, University of Tokyo.

Abstract

The aim of this study was to determine an effective dose of the contrast agent diatrizoate in healthy rabbits. This study included 14 rabbits receiving three different dosages of a solution containing 300 mg iodine/mL and 600 mg diatrizoate/mL (Dose 1, 2 mL/kg; Dose 2, 7 mL/kg; Dose 3, 10 mL/kg). Full body radiographs were obtained at 0, 15, 30, 45 and 60 minutes, and 12 and 24 hours after oral administration. Blood samples 60 minutes and 24 hours after administration and fecal dry matter after 24 hours were compared to preliminary samples. Recommended doses and times for radiography for luminal patency and visualization of each gastrointestinal segment are given. The evaluated blood parameters were within their respective reference intervals throughout this study. However, significant changes (P < 0.05) could be observed. A decrease in hematocrit at all three doses administered, an increase in urea that persisted for more than 24 hours after administration of 2 mL/kg and 10 mL/kg, and a short-term increase in creatinine after administration of 7 mL/kg could be observed. Glucose and sodium were still increased after administration of 10 mL/kg after 24 hours, while potassium decreased after administration of all three doses. The chloride concentration was still increased after 24 hours after administration of 7 mL/kg. Administration of 7 mL/kg and 10 mL/kg resulted in a significant decrease in the dry matter of feces. Five rabbits developed self-limiting diarrhea after administration of 10 mL/kg. Diatrizoate is a useful contrast agent in order to assess the passage through the intestine and achieve a good visualization of the gastrointestinal system. [ABSTRACT FROM AUTHOR]

Abstract

International audience; Isomeric states in isotopes in the vicinity of doubly-magic 208Pb were populatedfollowing reactions of a relativistic 208Pb primary beam impinging on a9Be fragmentation target. Secondary beams of 198,200,202,206Pb and 206Hg wereisotopically separated and implanted in a passive stopper positioned in thefocal plane of the GSI Fragment Separator. Delayed γ rays were detected withthe Advanced Gamma Tracking Array (AGATA). Decay schemes were reevaluatedand interpreted with shell-model calculations. The momentumdependentpopulation of isomeric states in the two-nucleon hole nuclei206Pb/206Hg was found to differ from the population of multi neutron-holeisomeric states in 198,200,202Pb.

Abstract

International audience; The lifetimes of the first 2+ excited states of 212,210Po were measured in two transfer reactions 208Pb(12C,8Be)212Po and 208Pb(12C,10Be)210Po by the Recoil Distance Doppler Shift (RDDS) method and by the Doppler Shift Attenuation method (DSAM), respectively. The derived absolute B(E2) values of 2.6(3) W.u. for 212Po and 1.83(28) W.u. for 210Po indicate low collectivity. It is shown that the properties of the yrast , , and states in both nuclei cannot be described consistently in the framework of nuclear shell models. It is also demonstrated in the case of 210Po that Quasi-particle Phonon Model (QPM) calculations cannot overcome this problem thus indicating the existence of a peculiarity which is neglected in both theoretical approaches.

29. Labial button technique for the treatment of a unilateral caudal mandibular fracture in a ferret (Mustela putorius furo).

Author

Brezina, Tina, Thöle, Milena, and Fehr, Michael

Abstract

Skull fractures in ferrets are rarely reported and established treatment methods for this species have not been published. A 3-year-old male chemically neutered pet ferret was presented with a malocclusion of the jaw after being bitten by a dog. Radiographs confirmed a unilateral caudal mandibular fracture. An esophageal tube was placed for alimentation during the healing process and the labial button technique for fracture stabilization was performed. The patient was hospitalized for 8 days, after which the sutures were removed, and the patient was discharged with a physiological occlusion of the jaw. Radiographs after 4 weeks and 4 months confirmed proper bone healing in the clinically unremarkable ferret. Due to their skull size and form, invasive methods, tape muzzles or other methods of fracture repair might not be suitable for every case of skull fracture in ferrets. Alternative methods, like the presented labial button technique, can provide sufficient stabilization for functional healing of a mandibular fracture in a ferret. The technique is easily performed, minimally invasive and requires no special material or instruments. [ABSTRACT FROM AUTHOR]

Abstract

The electromagnetic structure of 140Sm was studied in a low-energy Coulomb excitation experiment with a radioactive ion beam from the REX-ISOLDE facility at CERN. The 2+ and 4+ states of the ground-state band and a second 2+ state were populated by multistep excitation. The analysis of the differential Coulomb excitation cross sections yielded reduced transition probabilities between all observed states and the spectroscopic quadrupole moment for the 2+ 1 state. The experimental results are compared to large-scale shell model calculations and beyond-mean-field calculations based on the Gogny D1S interaction with a five-dimensional collective Hamiltonian formalism. Simpler geometric and algebraic models are also employed to interpret the experimental data. The results indicate that 140Sm shows considerable γ softness, but in contrast to earlier speculation no signs of shape coexistence at low excitation energy. This work sheds more light on the onset of deformation and collectivity in this mass region. 15 pages, 12 figures ispartof: Physical Review C vol:93 issue:5 status: published

Abstract

We present the results from an experiment dedicated to search for quadrupole-collective isovector valence-shell excitations, states with so-called mixed proton-neutron symmetry (MSS), of $^{212}\mathrm{Po}$. This nucleus was studied in an $\ensuremath{\alpha}\text{-transfer}$ reaction. The lifetimes of two short-lived excited states, candidates for the one-phonon MSS, were determined by utilizing the Doppler shift attenuation method. The experimental results are in qualitative agreement with a simple $\text{single-}j$ shell model calculation, which, together with the observed lack of quadrupole collectivity, indicates that the isovector nature of low-lying states is a property of the leading single-particle valence shell configuration.

Abstract

It was shown that the evolution of the $B(E2;{2}_{1}^{+}\ensuremath{\rightarrow}{0}_{1}^{+})$ values in $N$ = 80 isotones from Te to Nd is affected by the underlying subshell structure. This manifests itself in the observation of the local suppression of the $B(E2)$ value at $Z=58$ with respect to the neighboring nuclei $^{136}\mathrm{Ba}$ and $^{140}\mathrm{Nd}$. To investigate this shell sensitivity toward the $Z=64$ subshell gap, the $B(E2;{2}_{1}^{+}\ensuremath{\rightarrow}{0}_{1}^{+})$ value of the unstable nucleus $^{142}\mathrm{Sm}$ was measured utilizing the projectile Coulomb excitation technique. The radioactive ion beam (RIB) experiment was performed at the REX-ISOLDE facility at CERN. The $B(E2)$ value of $32\phantom{\rule{0.16em}{0ex}}(4)\phantom{\rule{0.16em}{0ex}}\mathrm{W}.\mathrm{u}.$ reflects the impact of the $\ensuremath{\pi}(1{g}_{7/2}\phantom{\rule{0.16em}{0ex}}2{d}_{5/2})$ subshell closure at $Z=64$ with respect to a linear scaling of collectivity with valence proton number.

35. Acid-base-balance status and blood gas analysis in rabbits with gastric stasis and gastric dilation.

Author

Brezina, Tina, Fehr, Michael, Neumüller, Manfred, and Thöle, Milena

Abstract

Background: The aim of this study was to analyse the acid-base-balance status and blood gas values in rabbits with gastric stasis and gastric dilation syndrome. Methods: Thirty rabbits with corresponding symptoms and radiographs were sampled before, during, and after treatment and an arterial acid-base-balance status and blood gas analysis was performed. Results: pCO 2 , HCO 3 , and base excess were significantly lower in animals that were presented 12 hours after the owner had registered signs of illness than animals presented within 6 hours. Of the examined rabbits, 57% had acidosis, 83% of which were of metabolic origin. The pH returned to normal after treatment in 94% of surviving animals (24/30). Conclusions: Gastric stasis and dilation syndrome has a considerable impact on the acid-base-balance status and blood gas analysis in rabbits and its measurement is therefore valuable for assessing the patient's status and adjusting the therapy accordingly to each animal's needs. Clinical relevance: Our findings underline the importance of a swift introduction of rabbits with gastric stasis and dilation syndrome into veterinary care to prevent further impairment of secondary findings such as metabolic acidosis.

37. Presumptive nonthyroidal illness syndrome in pet rabbits (Oryctolagus cuniculus).

Author

Thöle, Milena, Brezina, Tina, Fehr, Michael, and Schmicke, Marion

Abstract

Thyroid diseases are rarely diagnosed in pet rabbits and very little is known about the effects of systemic illnesses on thyroid hormone levels in this species. This brief communication compares the results of total thyroxine (T4, n = 44) and free T4 (n = 26) measurements in sick rabbits with total T4 (n = 56) and free T4 (n = 28) measurements from apparently healthy animals. Mean values of total and free T4 were significantly lower in sick animals, indicating nonthyroidal illness syndrome in the pet rabbit. Unlike in the dog, total and free T4 were both decreased to a similar degree in diseased rabbits. Rabbits with fractures and presumed obstructive ileus had particularly low total T4 levels. Total T4 values of rabbits suffering from urinary tract diseases were affected to a lesser extent. The effect of different diseases on free T4 values could not be evaluated on account of the small sample size. This study suggests that, similar to other species, total and free T4 measurement alone might not be sufficient to diagnose hypothyroidism in the pet rabbit due to the existence of nonthyroidal illness syndrome.

Abstract

International audience; Electromagnetic transition strengths and spectroscopic quadrupole moments for Sm-140 were measured by means of multi-step Coulomb excitation with radioactive beam at the ISOLDE facility at CERN. A complementary experiment was performed at the Heavy Ion Laboratory in Warsaw to assign spins for non-yrast states using the angular correlation technique. Based on the new experimental data previous spin assignments need to be revised.

39. TREATMENT OF UNILATERAL PERINEAL HERNIAS IN 2 MALE CHINCHILLAS (CHINCHILLA LANIGERA).

Author

Abstract

Two sexually intact adult male chinchillas were presented with a swelling in the perineal region. Radiographically both masses had a soft tissue opacity. Ultrasonography confirmed the tentative diagnosis of perineal hernia. In the first case the ultrasonographic examination revealed a fluid-filled structure inside the swelling, which was determined to be the urinary bladder. In the second case the hernia sac was filled with homogeneous tissue, belived to be fat. Subsequently, unilateral perineal herniorrhaphies including an internal obturator muscle flap transposition technique were performed. Both chinchillas recovered well with subsequent uneventful healing of the surgical sites. No long-term complications or recurrences of the perineal hernias were reported. This clinical report shows that perineal hernias occur in chinchillas and can be surgically treated with success. [ABSTRACT FROM AUTHOR]

Abstract

We report on the study of excited states in 92,94,96Kr populated via projectile Coulomb excitation at safe energies. The radioactive ion beams at energies of 2.85 MeV/u were delivered by the REX-ISOLDE facility at CERN and impinged on self-supporting 194,196Pt targets. The emitted γ -rays were detected by the Miniball detector-array. A detailed description of the experimental techniques used for extracting diagonal and transitional matrix elements and of the theoretical framework is given. The present experiment reveals the moderate evolution of the collective structure in the considered neutron-rich Kr isotopic chain, which is supported by the interacting boson model combined with the self-consistent mean-field method using a microscopic Gogny energy-density functional. The theory also suggests possible shape coexistence in the exotic nucleus 96Kr. ispartof: Nuclear Physics A vol:899 pages:1-28 status: published
