TL;DR: The ENDF/B-VII.1 library as mentioned in this paper is the most widely used data set for nuclear data analysis and has been updated several times over the last five years. But the most recent version of the ENDF-B-VI.0 library is based on the JENDL-4.0 standard.

TL;DR: In this paper, the authors measured the energy range of the Gamow window for the astrophysical $p$-process scenario and compared the results with predictions of the statistical model code NON-SMOKER using different input parameters.
Abstract: The $^{106}\mathrm{Cd}$($\ensuremath{\alpha},\ensuremath{\gamma})$$^{110}\mathrm{Sn}$ reaction cross section has been measured in the energy range of the Gamow window for the astrophysical $p$-process scenario. The cross sections for $^{106}\mathrm{Cd}$($\ensuremath{\alpha},n$)$^{109}\mathrm{Sn}$ and for $^{106}\mathrm{Cd}$($\ensuremath{\alpha},p$)$^{109}\mathrm{In}$ below the ($\ensuremath{\alpha},n$) threshold have also been determined. The results are compared with predictions of the statistical model code NON-SMOKER using different input parameters. The comparison shows that a discrepancy for $^{106}\mathrm{Cd}$($\ensuremath{\alpha},\ensuremath{\gamma})$$^{110}\mathrm{Sn}$ when using the standard optical potentials can be removed with a different \ensuremath{\alpha} + $^{106}\mathrm{Cd}$ potential. Some astrophysical implications are discussed.

TL;DR: In this article, the authors measured the energy range of the self-supporting $p$-process at the Notre Dame FN Tandem Van de Graaff accelerator with a pair of large volume Ge clover detectors in close geometry to maximize the detection efficiency.
Abstract: The cross section of the reaction $^{112}\mathrm{Sn}$($\ensuremath{\alpha},\ensuremath{\gamma})^{116}\mathrm{Te}$ has been measured in the energy range of astrophysical interest for the $p$-process. Highly enriched self-supporting $^{112}\mathrm{Sn}$ foils were bombarded with \ensuremath{\alpha} beams in the effective center of mass energy range from 7.59 to 11.42 MeV at the Notre Dame FN Tandem Van de Graaff accelerator. The characteristic activity of $^{116}\mathrm{Te}$ was counted with a pair of large volume Ge clover detectors in close geometry to maximize the detection efficiency. The cross section of the concurrent ($\ensuremath{\alpha},p$) reaction has also been measured. The results are compared with statistical model predictions for different global \ensuremath{\alpha}-nucleus potentials.

TL;DR: In this paper, a multilevel R-matrix theory has been used to estimate the energy of the N(p,{gamma}]-sup 16}O reaction with an S(0) value of 39.6 keV b.
Abstract: The {sup 15}N(p,{gamma}){sup 16}O reaction represents a breakout reaction linking the first and second cycles of the CNO cycles redistributing the carbon and nitrogen abundances into the oxygen range. The reaction is dominated by two broad resonances, at E{sub p}=338 and 1028 keV, and a direct capture contribution to the ground state of {sup 16}O. Interference effects between these contributions both in the low-energy region (E{sub p}<338 keV) and between the two resonances (338

TL;DR: Geant4 as discussed by the authors is a software toolkit for the simulation of the passage of particles through matter, which is used by a large number of experiments and projects in a variety of application domains, including high energy physics, astrophysics and space science, medical physics and radiation protection.
Abstract: Geant4 is a software toolkit for the simulation of the passage of particles through matter. It is used by a large number of experiments and projects in a variety of application domains, including high energy physics, astrophysics and space science, medical physics and radiation protection. Over the past several years, major changes have been made to the toolkit in order to accommodate the needs of these user communities, and to efficiently exploit the growth of computing power made available by advances in technology. The adaptation of Geant4 to multithreading, advances in physics, detector modeling and visualization, extensions to the toolkit, including biasing and reverse Monte Carlo, and tools for physics and release validation are discussed here.

TL;DR: High confidence in the MCNP6 code is based on its performance with the verification and validation test suites, comparisons to its predecessor codes, the regression test suite, its code development process, and the underlying high-quality nuclear and atomic databases.
Abstract: MCNP6 is simply and accurately described as the merger of MCNP5 and MCNPX capabilities, but it is much more than the sum of those two computer codes. MCNP6 is the result of five years of effort by ...

TL;DR: In this paper, the reduced electric quadrupole transition probability, B(E2)↑, from the ground state to the first-excited 2+ state of even-even nuclides are given in Table I.
Abstract: Adopted values for the reduced electric quadrupole transition probability, B(E2)↑, from the ground state to the first-excited 2+ state of even–even nuclides are given in Table I. Values of τ, the mean life of the 2+ state; E, the energy; and β, the quadrupole deformation parameter, are also listed there. The ratio of β to the value expected from the single-particle model is presented. The intrinsic quadrupole moment, Q0, is deduced from the B(E2)↑ value. The product E×B(E2)↑ is expressed as a percentage of the energy-weighted total and isoscalar E2 sum-rule strengths.
Table II presents the data on which Table I is based, namely the experimental results for B(E2)↑ values with quoted uncertainties. Information is also given on the quantity measured and the method used. The literature has been covered to November 2000.
The adopted B(E2)↑ values are compared in Table III with the values given by systematics and by various theoretical models. Predictions of unmeasured B(E2)↑ values are also given in Table III.
