Title: Monte Carlo approach to sequential {gamma}-ray emission from fission fragments

Abstract

A Monte Carlo simulation of the fission fragment statistical decay based on a sequential neutron followed by {gamma}-ray emission is proposed. The {gamma}-ray energy spectrum is calculated as a function of the mass of the fission fragments and integrated over the whole mass distribution. The prompt {gamma}-ray multiplicity distribution, both the average number of emitted {gamma} rays and the average {gamma}-ray energy as a function of the mass of the fission fragments [respectively, N{sub {gamma}}(A) and <{epsilon}{sub {gamma}}>(A)], are also assessed. The {gamma}-{gamma} correlations emitted from both light and heavy fragments are calculated as well as correlations between {gamma}-ray energies. Results are reported for the neutron-induced fission of {sup 235}U (at 0.53 MeV neutron energy) and for the spontaneous fission of {sup 252}Cf.
