Theoretical Calculations of n + ~(232,234,236,238,240)U Reaction Cross Sections

摘要

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.
