Theoretical Calculations of n + ^{232,234,236,238,240}U Reaction Cross Sections

Abstract

Consistent calculation and analysis of neutron scattering data of ^{232,234,236,238,240}U with a spherical optical model, the unified Hauser-Feshbach theory and the exciton model, the linear angular momentum–dependent exciton state density model, and the coupled channel theory are carried above the resolved resonance range and below 20 MeV based on the experimental data of total, nonelastic-scattering, fission, and other reaction cross sections and elastic-scattering angular distributions. Theoretical calculations are compared with experimental data and other evaluated data from ENDF/B-VII and JENDL-3.3.
