Abstract
Total reaction cross sections for -induced reactions are investigated over a wide energy range from 0 to 5000 MeV using an intranuclear cascade (INC) model. The model is an extension of the framework previously applied to nucleon-, deuteron-, and α-particle-induced reactions. The experimental data for (92% ), and are well reproduced using reconstructed in-medium two-body cross sections and parameters consistent with earlier studies. The discrete-level constraint (DLC) effect and the Coulomb effect are shown to make significant contributions that depend on both the target nucleus and the incident energy. The influence of the DLC is confined to a narrow low-energy region and is more pronounced for light targets, whereas the Coulomb effect plays a decisive role at low energies for all targets and becomes increasingly important for heavier nuclei. The trends of these contributions are consistent with those observed in total reaction cross sections induced by protons, deuterons, and α particles reported in previous works. The breakup of induced by the target potential is found to be non-negligible, with single-particle breakup channels such as -n or -p dominating the process. In particular, is emitted predominantly at very forward angles below 1400 MeV, where the Coulomb force acts effectively on charged particles. These results demonstrate that the extended INC model, which incorporates two quantum corrections (the Pauli principle and DLC) and properly accounts for the Coulomb interaction, is capable of describing total reaction cross sections for a wide range of target nuclei over energies extending from the very low-energy region up to 5000 MeV.
