Pre-equilibrium model evaluation of neutron spectra from proton-induced reactions

Abstract

Calculations of energy spectra of neutrons emitted from ($p,n$) reactions were performed on the basis of the pre-equilibrium exciton model. The results were compared with several experiments, covering the range from $A=27$ to $A=208$ of target masses, and from 17.6 to 63.8 MeV of incident proton energy. Within the limits of accuracy of both calculations and experimental data, the theoretical previsions were found adequate, and provided reasonable evaluations of the yields of pre-equilibrium neutron emissions.NUCLEAR REACTIONS ($p,n$) for $18<{E}_{p}<64$ MeV.
