Inclusive cross-sections of (p,xp) and (p,xα) reactions onFe56atEp=29.9MeV

Abstract

In this paper, we present new experimental data measured at E{sub p}= 29.9 MeV for the inclusive reactions (p,xp) and (p,x{alpha}) on nucleus {sup 56}Fe. We investigate the adequacy of the theoretical models in explaining the measured experimental data, and we determine the contributions of multistep direct and multistep compound processes in the formation of the cross-sections. We show that the traditional frameworks are valid for the description of the new experimental data, and our measurements agree with previous measurements for the (p,xp) and (p,x{alpha}) reactions on the {sup 54}Fe nucleus. The only exception is within the energy region of E{sub p}= 15 and 25 MeV for both reactions, where the cross-section for the {sup 56}Fe nucleus is smaller than the cross-section for the {sup 54}Fe nucleus.
