EVALUATION OF NEUTRON-INDUCED REACTION CROSS-SECTIONS FOR URANIUM ISOTOPES AT ENERGIES UP TO 100 MEV

Fission, (n,xn), as well as (n,pxn) reaction cross-sections for uraniu m nuclei with mass numbers from 232 to 238 at primary neutrons energie s from 1 up to 100 MeV were evaluated, using empirical ratios of the n eutron and fission channel widths. A modified version of the code ALIC E was used for the numerical calculations. The obtained cross-sections are compared with data from the BROND-2, JENDL-3, and ENDF/B-VI libra ries as well as with available experimental data and calculated result s obtained from the intranuclear cascade evaporation model.
