Prediction of the prompt neutron multiplicity distribution ν(A) for 235U(n,f) and 239Pu(n,f) in the incident energy range of multichance Fission
Measurements of fission fragment data at incident energies (En) up to several tens of MeV require prompt neutron multiplicity distribution ν(A) to determine the preneutron fragment properties. Those ν(A) data are not readily experimentally available. Consequently, model predictions of ν(A) at En where multichance fission occurs are needed. The Point-by-Point model of prompt emission provides the individual ν(A) of compound nuclei of the main and secondary nucleus chains that are undergoing fission at any En. Total ν(A) calculations for n + 235U and n + 239Pu are presented together with systematic behaviors of individual ν(A) with increasing energy.
