Light charged particle emission for p+54,56,57,58,natFe reactions

Abstract

The energy spectra and double differential cross sections of nucleon and the light composite particle (d, t, 3He and α) emissions are studied based on the exciton model included the improved Iwamoto–Harada model. All cross sections of proton induced reactions, angular distributions and energy spectra are consistent calculated and analyzed for 54,56,57,58,natFe at incident proton energies below 250MeV by using nuclear theoretical models which integrate the optical model, the intra-nuclear cascade model, direct, pre-equilibrium and equilibrium reaction theories. Theoretical calculated results are compared with existing experimental data.
