Calculation of particle emission rates for nucleon-induced reactions with non-equidistance spacing model dependence

Abstract EN

Nuclear emission rates for nucleon-induced reactions are theoretically calculated based on the one-component exciton model that uses state density with non-Equidistance Spacing Model (non-ESM).

Fair comparison is made from different state density values that assumed various degrees of approximation formulae, beside the zeroth-order formula corresponding to the ESM.

Calculations were made for 96Mo nucleus subjected to (N,N) reaction at Emax = 50 MeV.

The results showed that the non-ESM treatment for the state density will significantly improve the emission rates calculated for various exciton configurations.

Three terms might suffice a proper calculation, but the results kept changing even for ten terms.

However, five terms is found to give the most appropriate conditions for calculation time and accuracy.
