Calculations of Emission Neutron and Fission Product Yields for Intermediate Nucleon Reactions

We modified and tested our code system MCFx to produce the nuclear data library for ADS. MCFx calculates the reaction cross sections through intranuclear cascade, preequilibrium emission, and compound‐nucleus decay stages. The Monte Carlo model of preequilibrium nucleon emission was realized, tested, and included in MCFx. For fissile nuclei produced in the cascade + preequilibrium calculation, the calculated distributions of excitation energies, masses, and charges were used in further computing fission product yields by solving the one‐dimensional Schrodinger equation on mass asymmetry at scission point. The results of calculations are compared with the experimental data.
