Cross sections of proton- and neutron-induced reactions by the Liège intranuclear cascade model

Abstract

The purpose of the paper is mainly to test the validity of the Liege intranuclear cascade (INCL) model in calculating the cross sections of proton-induced reactions for cosmogenic nuclei using the newly compiled database of proton cross sections. The model calculations of He-3 display the rising tendency of cross sections with the increase of energy, in accordance with the experimental data. Meanwhile, the differences between the theoretical results and experimental data of production cross sections (Be-10 and Al-26) are generally within a factor of 3, meaning that the INCL model works quite well for the proton-induced reactions. Based on the good agreement, we predict the production cross sections of Al-26 from reactions n + Al-27, n + Si-28, and n + Ca-40 and those of Be-10 from reactions n + O-16 and n + Si-28. The results also show a good agreement with a posteriori excitation functions.
