A new proton spectra for C-nat(p,xp) reaction at E-p=7 and 30 MeV

Abstract

In this paper, we present a new measurement of the inclusive cross section (p,xp) reactions on Cu-nat at incident energies of E-p = 7 and 30 MeV. The (p,xp) reaction at E-p= 7 MeV on Cu-nat is measured for the first time and (p,xp) and (p,x alpha) inclusive cross section for the same target at E-p = 30 MeV is re-measured in order to improve the quality of the previous experimental data. For both energies, the mechanism of the pre-equilibrium reactions as well as the level of energy dependence are discussed and the adequacy of the theoretical models in explaining the newly measured experimental data is also assessed by comparing the experimental data with the results of the Hauser-Feshbach and Exciton models. We use the microscopic approach based on nucleon-nucleon interaction to produce the complex nuclear potential.
