Abstract :
Consistent calculation and analysis of neutron scattering data of 233,235,237U with optical model, semiclassical model including both the unified Hauser-Feshbach theory and the exciton model, the coupled channel theory, and distorted wave Born approximation were carried out in the En <= 20-MeV energy range based on the experimental data. In particular, the analysis includes the prompt fission neutron spectra and the double-differential cross section for neutron emission. Theoretical calculations are compared with recent experimental data and other evaluated data from ENDF/B-VI release 6 and JENDL-3.3.
