| contents | We present calculations of neutron thermal cross sections, Westcott factors, resonance integrals, Maxwellian-averaged cross sections, astrophysical reaction rates, and solar system $r$-process abundances using the latest data from the major evaluated nuclear libraries for 849 ENDF target materials. The recent release of ENDF/B-VIII.1 library, progress in $^{252}$Cf(SF) evaluation, extensive analysis of newly-evaluated neutron reaction cross sections, neutron covariances, and improvements in data processing techniques motivated us to calculate the nuclear industry and neutron physics parameters, produce $s$-process Maxwellian-averaged cross sections and astrophysical reaction rates, extract $r$-process abundances, systematically calculate uncertainties, and provide additional insights on currently available neutron-induced reaction data. |
