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 article, the GEANIE spectrometer was used to measure absolute partial cross sections for the production of discrete γ-rays using 60Ni(n, x n y p z α γ ) reactions with x ≤ 3, y ≤ 2 and z ≤ 4 in a total of 20 reaction channels.

TL;DR: In this paper, a coupled-channel optical model based on the soft rotor model and with spherical potential was employed to calculate the spin distribution in the pre-equilibrium reaction of the 150Sm(n,n′γ) reaction.
Abstract: The 150Sm(n,n′γ) reaction was measured from En = 1 to 15 MeV at the Los Alamos Neutron Science Cemter (LANSCE). The γ rays were detected with the Compton‐suppressed Germanium Array for Neutron Induced Excitations (GEANIE). Measured γ‐ray excitation functions were converted to partial γ‐ray cross sections, Twenty four individual γ‐rays up to Ex = 1.8 MeV in 150Sm were measured. Results are compared with enhanced Hauser Feshbach model calculations: the spin distribution in the pre‐equilibrium reaction is calculated with the quantum mechanical model of Feshbach, Kerman and Koonin. The particle transmission coefficients were calculated with two different global optical model potential parameter sets. We employed the coupled‐channel optical model based on the soft rotor model and with spherical potential.

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 ...
