Physics ,QC1-999 - Abstract
We present a direct method to measure fission product yield distributions (FPY) and isomeric yield ratios (IYR) for spontaneous fission (SF) fragments. These physical properties are of utmost importance to the understanding of basic nuclear physics, the astrophysical rapid neutron capture process ('r process') of nucleosynthesis, neutron star composition, and nuclear reactor safety. With this method, fission fragments are produced by spontaneous fission from a source that is mounted in a cryogenic stopping cell (CSC), thermalized and stopped within it, and then extracted and transported to a multiple-reflection time-of-flight mass-spectrometer (MR-TOF-MS). We will implement the method at the FRS Ion Catcher (FRS-IC) at GSI (Germany), whose MR-TOF-MS relative mass accuracy (~ 10-7) and resolving power (~ 600,000 FWHM) are sufficient to separate all isobars and numerous isomers in the fission fragment realm. The system's essential element independence and its fast simultaneous mass measurement provide a new direct way to measure isotopic FPY distributions, which is complementary to existing methods. It will enable nuclide FPY measurements in the high fission peak, which is hardly accessible by current techniques. The extraction time of the CSC, tens of milliseconds, enables a direct measurement of independent fission yields, and a first study of the temporal dependence of FPY distributions in this duration range. The ability to resolve isomers will further enable direct extraction of numerous IYRs while performing the FPY measurements. The method has been recently demonstrated at the FRS-ICr for SF with a 37 kBq 252Cf fission source, where about 70 different fission fragments have been identified and counted. In the near future, it will be used for systematic studies of SF with a higher-activity 252Cf source and a 248Cm source. The method can be implemented also for neutron induced fission at appropriate facilities.

- Abstract
Long-lived isomeric states in $^{97}$Ag and $^{101−109}$In were investigated with the FRS Ion Catcher at GSI. In the isotope $^{97}$Ag, a long-lived (1/2−) isomeric state was discovered, and its excitation energy was determined to be 618(38) keV. This is simultaneously the first discovery of a nuclear isomeric state by multiple-reflection time-of-flight mass spectrometry. The measured excitation energies were compared to large-scale shell-model calculations, which indicated the importance of core excitation around $^{100}$Sn. Furthermore, advanced mean-field calculations for the $^{97}$Ag nucleus and relevant neighboring nuclei were performed, which have contributed to a better understanding of the repetitive appearance of certain isomeric structures in neighboring nuclei, and which have supported the discovery of the isomeric state in $^{97}$Ag in a global shell-evolution scheme.

The FRS Ion Catcher at GSI enables precision experiments with thermalized projectile and fission fragments. At the same time it serves as a test facility for the Low-Energy Branch of the Super-FRS at FAIR. The FRS Ion Catcher has been commissioned and its performance has been characterized in five experiments with 238U and 124Xe projectile and fission fragments produced at energies in the range from 300 to 1000 MeV/u. High and almost element-independent efficiencies for the thermalization of short-lived nuclides produced at relativistic energies have been obtained. High-accuracy mass measurements of more than 30 projectile and fission fragments have been performed with a multiple-reflection time-of-flight mass spectrometer (MR-TOF-MS) at mass resolving powers of up to 410,000, with production cross sections down to the microbarn-level, and at rates down to a few ions per hour. The versatility of the MR-TOF-MS for isomer research has been demonstrated by the measurement of various isomers, determination of excitation energies and the production of a pure isomeric beam. Recently, several instrumental upgrades have been implemented at the FRS Ion Catcher. New experiments will be carried out during FAIR Phase-0 at GSI, including direct mass measurements of neutron-deficient nuclides below 100Sn and neutron-rich nuclides below 208Pb, measurement of β-delayed neutron emission probabilities and reaction studies with multi-nucleon transfer. peerReviewed

Physics ,ddc:530 - Abstract
In this doctoral work, a novel method for simultaneous measurement of masses, isomer excitation energies, half-lives, and decay branching ratios of exotic nuclei has been developed, implemented, and used at the FRS Ion Catcher (FRS-IC) experiment located at the GSI accelerator facility in Darmstadt, Germany. The method utilizes the advantages of in-flight production and separation of exotic nuclei at relativistic energies in the fragment separator (FRS), controllable storage of the ions of interest and retrapping of their decay recoils in a gas-filled cryogenic stopping cell (CSC), and fast, accurate and broadband measurement with a multiple reflection time-of-flight mass spectrometer (MR-TOF-MS). The feasibility of the method has been demonstrated in pilot measurements with the FRS Ion Catcher. The measurements have been performed with the nuclide 216Po produced by an internal alpha-recoil source and with the nuclide 119Sb and its isomer produced by fragmentation of 238U primary beam at an energy of 300 MeV/u. It has been shown that the ions can be stored in the CSC for controllable durations of up to 10 seconds without non-nuclear-decay losses. The alpha-decay of 216Po and the internal transition of the 119m2Sb isomer produced in the FRS have been investigated by observing simultaneous decay of the mother nuclides and growth of the daughter nuclides. The measured half-life value for 216Po of (145 ± 11) ms is consistent with the literature value of (145 ± 2) ms; and the measured half-life of 119m2Sb of (776 ± 181) ms is consistent with the literature value of (850 ± 90) ms. For the 119m2Sb isomer, for which it is energetically possible to undergo three different types of decay, the decay branching ratios have been measured directly for the first time. It has been experimentally confirmed that the isomer decays by internal transition, whereas the probabilities for beta+- and beta- -decays are consistent with 0. The masses of the ground and isomeric states of 119Sb have been measured directly for the first time, as well. Previously, the excitation energy and the spin assignment of the 119m2Sb isomer had not been unambiguously established. The results of gamma-ray spectroscopy experiments contradicted each other. In this work, it has been confirmed that the 119m2Sb isomeric state has an energy level of 2841.7 keV. The obtained results indicate that the adopted assignment for the excitation energy and the spin of 119m2Sb is not correct. In addition, within the frame of this thesis, a number of technical improvements and upgrades have been introduced to the FRS Ion Catcher setup. (i) A new calibration 228Th recoil ion source has been installed inside the CSC. This source and a discharge source have been extensively characterized. (ii) The vacuum system has been upgraded, which, in combination with the extended RFQ beamline, has resulted in higher possible areal densities of the CSC operation. The safe long-term operation of the CSC at areal densities of helium buffer gas of up to 10 mg/cm2 has been demonstrated, which is almost a factor of two higher than in the past. The increase in the buffer gas areal density leads to the corresponding increase in the stopping efficiency of the CSC. (iii) In order to increase the selectivity of ion transport, two new techniques have been developed and implemented: the isolation-dissociation-isolation (IDI) method in the RFQ beamline and the separation by ion mobility at the RF carpet. Also, in this work, characterization studies have been conducted. (i) The cleanliness of the CSC and the charge states of the thermalized and extracted ions have been investigated. It has been confirmed from the measurements of ions of more than 25 different chemical elements that the charge states are governed by the ionization potential of N2 molecules, which are the dominant contaminant of the helium buffer gas in the present setup. (ii) Rate capability studies of the CSC have been conducted. (iii) In addition, the homogeneity of the matter in the beamline of the FRS has been studied with the FRS Ion Catcher. It has been observed that, for 238U primary beam with an initial energy of 300 MeV/u, the measured width of the range distribution of the ions sigma = (7.8 ± 0.4) mg/cm2 is more than a factor of five larger than the calculated collisional straggling. The results indicate that the the range distribution of the ions for these experimental conditions is dominated by the contribution of the charge-exchange range straggling. A thickness variation of the matter in the beamline of the FRS corresponding to ~ 20-30 µ of aluminum has also been measured. Im Rahmen dieser Doktorarbeit wurde eine neuartige Methode zur gleichzeitigen Messung von Massen, Isomerenanregungsenergien, Halbwertszeiten und Zerfalls-Verzweigungsverhältnissen exotischer Kerne entwickelt, implementiert und eingesetzt am FRS Ion Catcher-Experiment an der GSI-Beschleunigeranlage in Darmstadt, Deutschland. Diese Methode nutzt die Vorteile der Produktion und Trennung exotischer Kerne bei relativistischen Energien im Fragmentseparator (FRS), die kontrollierte Speicherung der Ionen von Interesse und des Einfangs ihrer Tochterkerne in einer gasgefüllten kryogenen Stoppzelle (cryogenic stopping cell, CSC) und die schnelle, genaue und breitbandige Messung mit einem Multireflexions-Flugzeitmassenspektrometer (multiple reflection time-of-flight mass spectrometer, MR-TOF-MS). Die Machbarkeit der Methode wurde in Pilotmessungen mit dem FRS-Ion-Catcher demonstriert. Diese Messungen wurden mit dem Nuklid 216Po durchgeführt, das von einer internen Quelle erzeugt wurde, und mit dem Nuklid 119Sb und seinem Isomer, die durch Fragmentation eines 238U Primärstrahls bei einer Energie von 300 MeV/u erzeugt wurden. Es konnte gezeigt werden, dass die Ionen für eine wählbare Zeitdauer von bis zu 10 Sekunden in der CSC gespeichert werden können, ohne dass Verluste, abgesehen von radioaktiven Zerfällen, auftreten. Der alpha-Zerfall von 216Po und die innere Konversion des im FRS produzierten 119m2Sb-Isomers wurden durch die gleichzeitige Beobachtung des Zerfalls der Mutterkerne und des Wachstums der Tochterkerne untersucht. Der gemessene Wert der Halbwertszeit für 216Po von (145 ± 11) ms stimmt mit dem Literaturwert von (145 ± 2) ms überein; und die gemessene Halbwertszeit von 119m2Sb von (776 ± 181) ms stimmt mit dem Literaturwert von (850 ± 90) ms überein. Für das Isomer 119m2Sb, für das drei verschiedene Zerfallsarten energetisch möglich sind, wurden die Zerfalls-Verzweigungsverhältnisse erstmals direkt gemessen. Es wurde experimentell bestätigt, dass das Isomer durch innere Konversion zerfällt, während die Wahrscheinlichkeiten für beta+- und beta- -Zerfälle mit 0 übereinstimmen. Die Massen des Grundzustands und des Isomers von 119Sb wurden ebenfalls zum ersten Mal direkt gemessen. Bisher waren die Anregungsenergie und die Spinzuordnung des 119m2Sb-Isomers nicht eindeutig bestimmt worden. Die Ergebnisse von mehreren Gammaspektroskopie-Experimente widersprachen sich. In Rahmen dieser Doktorarbeit wurde bestätigt, dass das Isomer 119m2Sb eine Anregungsenergie von 2841.7 keV hat. Die angenommene Zuordnung für die Anregungsenergie und den Spin von 119m2Sb ist hingegen nicht korrekt. Darüber hinaus wurden im Rahmen dieser Arbeit einige technische Verbesserungen und Erweiterungen des FRS-Ion-Catcher-Exoeriments vorgenommen. (i) Im der CSC wurde eine neue 228Th-Kalibrationsionenquelle installiert. Diese Quelle und eine Entladungsquelle wurden ausführlich untersucht und charakterisiert. (ii) Das Vakuumsystem wurde aufgerüstet, was in Kombination mit der erweiterten RFQ-Strahlführung zu einer höheren maximalen Flächendichte der CSC ermöglicht. Es wurde der sichere Langzeitbetrieb der CSC bei Flächendichten des Helium-Puffergases von bis zu 10 mg/cm2 gezeigt; diese Flächendichte beträgt das zweifache des bisher erreichten Wertes. Die Erhöhung der Flächendichte führt zu einer entsprechenden Erhöhung der Stoppeffizienz der CSC. (iii) Um die Selektivität des Ionentransports zu erhöhen, wurden zwei neue Techniken entwickelt und implementiert: die Isolations-Dissoziations-Isolations (IDI) Methode in der RFQ-Strahlführung und die Ionenseparation am RF-Carpet durch die Ionenmobilität. Die Sauberkeit der CSC und die Ladungszustände der thermalisierten und extrahierten Ionen von mehr als 25 verschiedenen chemischen Elementen wurden untersucht. Der Einfluss der Raumladung auf die Leistungsfähigkeit des RF-Carpets wurde untersucht und als vernachlässigbar gefunden. Darüber hinaus wurde die Homogenität der Materie im FRS mit dem FRS-Ion-Catcher untersucht.

Neutron-deficient iodine isotopes, 116 I and 114 I, were produced at relativistic energies by in-flight fragmentation at the Fragment Separator (FRS) at GSI. The FRS Ion Catcher was used to thermalize the ions and to perform highly accurate mass measurements with a Multiple-Reflection Time-of-Flight Mass-Spectrometer (MR-TOF-MS). The masses of both isotopes were measured directly for the first time. The half-life of the 114 I was measured by storing the ions in an RF quadrupole for different storage times and counting the remaining nuclei with the MR-TOF-MS. The measured half-life was used to assign the ground state to the measured 114 I ions. Predictions on the possible α -decay branch for 114 I are presented based on the reduced uncertainties obtained for the Q α -value. Systematic studies of the mass surface were performed with the newly obtained masses, showing better agreement with the expected trend in this mass region. [ABSTRACT FROM AUTHOR]

- Abstract
In the present work we analyzed the influence of torch discharge plasma heterogeneity on the character of electromagnetic field attenuation along the discharge axis. A discharge burning in air at atmospheric pressure was analyzed. When taking discharge filament heterogeneity into account, two factors were considered: axial heterogeneity of discharge filament specific conductivity and diminishing of the filament radius along the discharge axis, i.e. changes in its shape. Axial distribution of discharge plasma specific conductivity was determined on basis of axial distribution of gas temperature. The gas temperature was measured on basis of relative intensity of rotational transitions of hydroxyl 3064 Å molecular band. The electrodynamic task was solved on basis of discharge filament model as a heterogeneous current line. When making calculations the obtained axial distribution of discharge plasma specific conductivity was taken into account. The discharge filament shape was assumed to be conical. As a result of calculations it was ascertained that electromagnetic field attenuation along the discharge axis proceeds under the linear law, which is in agreement with the experimental data obtained earlier. It was also revealed that torch discharge plasma is characterized by higher nonequilibrium than it follows from the analysis of the balance of chemical reactions in discharge plasma.

A novel method for simultaneous measurement of masses, Q-values, isomer excitation energies, half-lives and decay branching ratios of exotic nuclei has been demonstrated. The method includes first use of a stopping cell as an ion trap, combining storage of mother and daughter nuclides for variable durations in a cryogenic stopping cell (CSC), and afterwards the identification and counting of them by a multiple-reflection time-of-flight mass spectrometer (MR-TOF-MS). We utilized our method to record the decay and growth of the 216Po and 212Pb isotopes (alpha decay) and of the 119m2Sb isomer ( t 1 / 2 = 850 ± 90 ms) and 119gSb isotope (isomer transition), obtaining half-lives consistent with literature values. The amount of non-nuclear-decay losses in the CSC up to ∼ 10 s is negligible, which exhibits its extraordinary cleanliness. For 119Sb isotopes, we present the first direct measurements of the mass of its ground state, and the excitation energy and decay branching ratios of its second isomeric state (119m2Sb). This resolves discrepancies in previous excitation energy data, and is the first direct evidence that the 119m2Sb isomer decays dominantly via γ emission. These results pave the way for the measurement of branching ratios of exotic nuclei. [ABSTRACT FROM AUTHOR]
