Monte-Carlo Simulation of Energy and Angular Distributions of Emitted Neutrons From a Given Fission Fragment

The neutron angular and energy distributions were calculated by using Monte-Carlo method for a given ²⁵²Cf binary fission fragment. The conditions and steps of the calculation were specified, and the results were presented. The interference of the neutrons from one fragment to those from the complementary fragment was analyzed. This simulation could work with the measured neutron spectra for a given fission fragment and give a theoretical reference for the relevant experimental measurements.
