Abstract

Uncertainties in nucleosynthesis models originating from uncertainties in astrophysical reaction rates were estimated in a Monte Carlo variation procedure. Thousands of rates were simultaneously varied within individual, temperature-dependent errors to calculate their combined effect on final abundances. After a presentation of the method, results from application to three different nucleosynthesis processes are shown: the γ-process and the s-process in massive stars, and the main s-process in AGB stars (preliminary results). Thermal excitation of nuclei in the stellar plasma and the combined action of several reactions increase the final uncertainties above the level of the experimental errors. The total uncertainty, on the other hand, remains within a factor of two even in processes involving a large number of unmeasured rates, with some notable exceptions for nuclides whose production is spread over several stellar layers and for s-process branchings.

Many more nuclear transitions have to be known in the determination of stellar reactivities for trans-iron nucleosynthesis than for reactions of light nuclei. This requires different theoretical and experimental approaches. Some of the issues specific for trans-iron nucleosynthesis are discussed., 6 pages, 3 figures; invited talk at Int.

Abstract

The cross sections of the 162Er(α,γ)166Yb and 162,164,166Er(α,n)165,167,169Yb reactions have been measured at MTA Atomki. The radiative alpha capture reaction cross section was measured between Ec.m. = 11.21 MeV and Ec.m. = 16.09 MeV just above the astrophysically relevant energy region (which lies between 7.8 and 11.48 MeV at T9 = 3 GK). The 162Er(α,n)165Yb, 164Er(α,n)167Yb and 166Er(α,n)169Yb reactions were studied between Ec.m. = 12.19 and 16.09 MeV, Ec.m. = 13.17 and 16.59 MeV and Ec.m. = 12.68 and 17.08 MeV, respectively. The aim of this work is to provide experimental data for modeling the γ process which is thought to be responsible for the production of the proton-rich isotopes heavier than iron.

Abstract

Current hydrodynamical simulations of core collapse supernovae find proton-rich early ejecta. At the same time, the models fail to eject neutron-rich matter, thus leaving the origin of the main r-process elements unsolved. However, the proton-rich neutrino-driven winds from supernovae have been identified as a possible production site for light n-capture elements beyond iron (such as Ge, Sr, Y, Zr) through the νp-process. The detailed nucleosynthesis patterns of the νp-process depend on the hydrodynamic conditions and the nuclear reaction rates of key reactions. We investigate the impact of reaction rate uncertainties on the νp-process nucleosynthesis.

Abstract

Although the detailed conditions for explosive nucleosynthesis are derived from astrophysical modeling, nuclear physics determines fundamental patterns in abundance yields, not only for equilibrium processes. Focussing on the nu-p- and the gamma-process, general nucleosynthesis features within the range of astrophysical models, but (mostly) independent of details in the modelling, are presented. Remaining uncertainties due to uncertain Q-values and reaction rates are discussed., Comment: 6 pages, 6 color figures; talk given at OMEG11 on November 14th, 2011; published in the proceedings of Origin Of Matter and Evolution Of Galaxies 2011; this version contains updated references and figures in full color

Abstract

We have analyzed, calculated and extended the modification of Maxwell’s equations in a complex Minkowski metric, M4 in a C2 space using the SU2 gauge, SL(2,c) and other gauge groups, such as SUn for n>2 expanding the U1 gauge theories of Weyl. This work yields additional predictions beyond the electroweak unification scheme. Some of these are: 1) modified gauge invariant conditions, 2) short range non‐Abelian force terms and Abelian long range force terms in Maxwell’s equations, 3) finite but small rest of the photon, and 4) a magnetic monopole like term and 5) longitudinal as well as transverse magnetic and electromagnetic field components in a complex Minkowski metric M4 in a C4 space.

Abstract

Astrophysical S‐factors of (p, n) reactions on 99Ru, 100Ru, 101Ru, and 102Ru were derived from the sum of experimental isomeric and ground states cross sections measured in the incident proton energy range of 5–9 MeV. They were compared with Hauser‐Feshbach statistical model predictions of the NON‐SMOKER code. Good agreement was found in the majority of cases. Reaction rates were derived up to 8.7 GK stellar temperature by combining experiment and theory.

Abstract

Recent attempts to consider isolated particles and real constitutive wave elements as localized, extended spacetime structures (i.e., moving within time‐like hypertubes or branes are developed within a causal extension of the Feynman‐Gell‐Mann electron model. These extended structures contain real internal motions, (i.e., internal hidden parameters) locally correlated with the “hidden parameters” describing the local collective motions of the corresponding pilot‐waves. Recent experimental evidence is briefly discussed.

Abstract

Neutron‐induced fission cross‐sections of minor actinides have been measured at the white neutron source n_TOF at CERN, Geneva. The studied isotopes include 233U, interesting for Th/U based nuclear fuel cycles, 241,243Am and 245Cm, relevant for transmutation and waste reduction studies in new generation fast reactors (Gen‐IV) or Accelerator Driven Systems. The measurements take advantage of the unique features of the n_TOF facility, namely the wide energy range, the high instantaneous neutron flux and the low background. Results for the involved isotopes are reported from ∼30 meV to around 1 MeV neutron enegy. The measurements have been performed with a dedicated Fission Ionization Chamber (FIC), relative to the standard cross‐section of the 235U fission reaction, measured simultaneously with the same detector. Results are here reported.

Abstract

Nucleosynthesis processes involve reactions on several thousand nuclei, both close to and far off stability. The preparation of reaction rates to be used in astrophysical investigations requires experimental and theoretical input. In this context, two interesting aspects are discussed: (i) the relevant gamma transition energies in astrophysical capture reactions, and (ii) the newly discovered Coulomb suppression of the stellar enhancement factor. The latter makes a number of reactions with negative Q value more favorable for experimental investigation than their inverse reactions, contrary to common belief., Comment: 5 pages, 5 figures, to appear in the proceedings of CGS 13 (Int.

Abstract

The cross sections of the astrophysically relevant 85$Rb(p,n)85Srg,m reaction have been measured between Ec.m. = 2.16 and 3.96 MeV. The cross sections have been derived by measuring the gamma radiation following the beta decay of the reaction products. A comparison with the predictions of Hauser-Feshbach calculations using the NON-SMOKER code confirms a recently derived modification of the global optical proton potential.

Abstract

Nucleosynthesis of heavy elements requires the use of different experimental and theoretical methods to determine astrophysical reaction rates than light element nucleosynthesis. Additionally, there are also larger uncertainties involved in the astrophysical models, both because the sites are not well known and because of differing numerical treatments in different models. As an example for the latter, the production of p-nuclei is compared in two different stellar models, demonstrating that a model widely used for postproduction calculations may have a zone grid too coarse to follow the synthesis of p-nuclei in detail.

Abstract

The neutron capture cross sections of 204Pb and 206Pb have been measured at the CERN n_TOF installation using the time of flight method with the pulse height weighting technique. In a preliminary analysis of 204Pb we have determined by first time the capture cross sections for two strong s‐wave resonances below 2.5 keV, which seem to enhance the Maxwellian Averaged Cross Section at kT = 5 keV by about a factor of two with respect to the value assumed so far. In 206Pb we have determined capture cross sections for a large number (97) of resonances, which were not reported in the two previous capture measurements. We discuss preliminary implications of the new cross sections in the stellar nucleosynthesis of the Pb isotopes.

Abstract

We measured the neutron capture cross section of 139La relative to 197Au in the energy range of 0.6 eV to 9 keV at n_TOF, the neutron time‐of‐flight facility at CERN. After a description of the experimental apparatus, we discuss data analysis procedures. The data were fitted using R‐matrix formalism to extract resonance parameters which, in turn, were used to calculate average level spacings D0 = 268 ± 22 eV and D1 < 250 eV, and neutron strength functions S0 = (0.79 ± 0.03)×10−4 and S1 = (0.73 ± 0.05)×10−4 for s‐ and p‐wave resonances. The data also were used to determine Maxwellian‐averaged neutron capture cross sections which, in turn, were used to calculate the 139La abundance synthesized in a stellar model of the main component of the s process.

Abstract

For more than 100 years scientists have attempted to determine the truth or falsity of claims that some people are able to describe and experience events or information blocked from ordinary perception. For the past 25 years, the authors of this paper – together with researchers in laboratories around the world — have carried out experiments in remote viewing. The evidence for this mode of perception, or direct knowing of distant events and objects, has convinced us of the validity of these claims. It has been widely observed that the accuracy and reliability of this sensory awareness does not diminish with either electromagnetic shielding, nor with increases in temporal or spatial separation between the percipient and the target to be described. Modern physics describes such a time‐and‐space independent connection between percipient and target as nonlocal.In this paper we present a geometrical model of space‐time, which has already been extensively studied in the technical literature of mathematics and physics. This eight‐dimensional metric is known as “complex Minkowski space,” and has been shown to be consistent with our present understanding of the equations of Newton, Maxwell, Einstein, and Schrodinger. It also has the interesting property of allowing a connection of zero distance between points in the complex manifold, which appear to be separate from one another in ordinary observation. We propose a model that describes the major elements of experimental parapsychology, and at the same time is consistent with the present highly successful structure of modern physics.For more than 100 years scientists have attempted to determine the truth or falsity of claims that some people are able to describe and experience events or information blocked from ordinary perception.

Abstract

We are developing an updated library with reaction rates important for the study of the astrophysical rp‐ process. It includes both experimental and theoretical rates parametrized in terms of the standard REACLIB format. The experimental data contain various compilations updated with the most recent data. The theoretical data are taken from shell‐model calculations whenever available otherwise statistical Hauser‐Feshbach calculations were used. All theoretical rates were recalculated using the latest reaction Q‐values. All new rates include stellar enhancement factors. The data will be accessed through a convenient web interface. It is anticipated that this JINA project evolves into an evaluated public data archive for reaclib library data.

In the present work both the (α,γ) and (p,γ) cross sections on the p‐nucleus 106Cd have been measured in the energy range relevant to the astrophysical p‐process. The results are compared with the predictions of the statistical model calculations implemented with the NON‐SMOKER code using different input parameters. The proton capture cross section has also been measured for 108Cd.The α + 106Cd optical potential, an important input parameter for the 106Cd(α,γ) reaction rate determination, can be determined directly by measuring the deviation from the Rutherford scattering in the 106Cd(α,α)106Cd elastic scattering experiment. This experiment has also been performed in a wide angular range and the results are compared with different global optical potentials.

Abstract

Accurate and reliable neutron capture cross section data for actinides are necessary for the proper design, safety regulation and precise performance assessment of transmutation devices such as Fast Critical Reactors or Accelerator Driven Systems. In particular, the neutron capture cross sections of 237Np, 240Pu and 243Am play a key role in the design and optimization of strategies for the Transmutation of Nuclear Waste. The listed cross sections have been measured in 2004 at n_TOF [1] with a high accuracy due to a combination of features unique in the world: high instantaneous neutron fluence and excellent energy resolution of the n_TOF facility, innovative Data Acquisition System based on flash ADCs and the use of a high performance BaF2 Total Absorption Calorimeter as a detection device.

Abstract

In order to improve the reliability of statistical model calculations in the region of heavy proton rich nuclei several elastic alpha scattering experiments have been carried out at low bombarding energies on various even‐even and semi‐magic nuclei. The extracted local optical potential parameters can be compared with the predictions of global alpha potentials. A study on 112,124Sn(α,α)112,124Sn has been made to test the global alpha potentials at both the proton and neutron rich sides of an isotopic chain. The present work describes the experimental challenges of high precision scattering experiments at low energy.

Abstract

PACS; International audience; A series of measurements of 237Np fission cross section have been performed at the CERN spallation neutron facility n_TOF which covers a wide energy range from 1 eV up to 250 MeV. A fast ionization chamber (FIC) was used as a fission fragment detector with registration efficiency of not less than 97 %. Particular attention was paid to correct the fission cross section with use of 235U standard. Total experimental uncertainties are determined to be at the level of 3%. Analysis of the experimental data in the restricted neutron energy from 5 eV up to 1 MeV showed a systematic deviation from evaluated data (ENDF/B-VI). This discrepancy amounts to up to a factor 3 for resolved resonances in the neutron energy range of 5 eV - 2 KeV, and is in good agreement with some previous experiments. A similar disagreement at the level of 6-7% was found for higher energies around the threshold (En = 300 keV-1 MeV). This energy range is essential for the transmutation of neptunium in ADS or fast reactors. It is concluded that an updated evaluation of nuclear data for 237Np is required

Abstract

The cross sections of the 162Er(α,γ)166Yb and 162,164,166Er(α,n)165,167,169Yb reactions have been measured at MTA Atomki. The radiative alpha capture reaction cross section was measured between Ec.m. = 11.21 MeV and Ec.m. = 16.09 MeV just above the astrophysically relevant energy region (which lies between 7.8 and 11.48 MeV at T9 = 3 GK). The 162Er(α,n)165Yb, 164Er(α,n)167Yb and 166Er(α,n)169Yb reactions were studied between Ec.m. = 12.19 and 16.09 MeV, Ec.m. = 13.17 and 16.59 MeV and Ec.m. = 12.68 and 17.08 MeV, respectively. The aim of this work is to provide experimental data for modeling the γ process which is thought to be responsible for the production of the proton-rich isotopes heavier than iron.

Abstract

The South Pole Infrared Explorer is the name given a series of experiments to determine the suitability of the South Pole as a site for near infrared astrophysics observations. For the first phase of this project we have constructed a 60 cm telescope and a near infrared imaging spectrometer. With this instrumentation we plan to carry out a program of measurements to test the qualities of the site. We also plan to carry out a survey for faint galaxies. Between December of 1993 and February of 1994 we began to place the equipment at the Pole. Since then, the telescope and instrumentation have survived their first winter of operation. In this paper we describe the experiments and our experiences.

Abstract

Spin‐nonconserving electron transfer processes violating the ‘‘Wigner rule’’ have been studied for slow multiply charged ion‐atom collisions. Experimentally a strong population of highly metastable sodium‐like quartet states in low energy Fe17+ + He single collision events has been observed. The possibility of double‐electron capture plus spin‐flip mechanisms has been discussed experimentally and theoretically, Our theoretical model using time dependent perturbation theory predicts that spin‐flip processes are as likely as no spin flip under the conditions of our experiment.

Abstract

State‐selective cross sections σ+*(nl) have been measured for ionization‐excitation of helium in collisions with fully stripped ions. The energies of the H+, Li3+, B5+, and C6+ were .83 MeV/u and 1.60 MeV/u. These relate to collision velocities of 5.8 and 8.0 a.u. Data for the Lyman series, He+(np→1s), have been measured by observation of the extreme ultra‐violet spectra in the 22 to 31 nm wavelength range. The 2p‐ 1s data is presented and analyzed in terms of a simple power law dependence on the projectile charge state, Zpn. For the two equivelocity series of cross sections the powers, n, derived from least squares fits to the data were 2.89±0.3 and 2.83±0.4.

Abstract

Current hydrodynamical simulations of core collapse supernovae find proton-rich early ejecta. At the same time, the models fail to eject neutron-rich matter, thus leaving the origin of the main r-process elements unsolved. However, the proton-rich neutrino-driven winds from supernovae have been identified as a possible production site for light n-capture elements beyond iron (such as Ge, Sr, Y, Zr) through the νp-process. The detailed nucleosynthesis patterns of the νp-process depend on the hydrodynamic conditions and the nuclear reaction rates of key reactions. We investigate the impact of reaction rate uncertainties on the νp-process nucleosynthesis. [ABSTRACT FROM AUTHOR]
