Dependence and influence of projectile energy and target mass on the production of light charged particles and intermediate mass fragments in proton induced reactions
Calculations were performed for proton induced spallation reactions over a wide range of atomic masses on the targets: ^{12}C, ^{27}Al, ^{nat}Ni, ^{108}Ag and ^{197}Au using an Intra-nuclear Cascade Model (INCL4.6) with coalescence which includes the emission of protons, light clusters (d–^{4}He), and intermediate mass fragments (up to A=8) formed by the nucleons during the first stage of the reaction. The emission of particles from excited cascade residua are described using three different theoretical models SMM, ABLA07, and GEMINI++. A comparison of calculations with experimental double differential cross–sections d^{2}σ/dΩdE for light charged particles and selected intermediate mass fragments was studied at proton beam energies from 1.2−2.5 GeV. Systematic deviations of the simulated cross sections from the experimental data were found for both light charged particles and intermediate mass fragments.
