Double Differential Charged Particle Emission Cross Sections and Stopping Power Calculations for Structural Fusion Materials 58,60Ni

Abstract

In this study, double differential light charged particle emission cross section, which is a fundamental data to determine nuclear heating and material damages in structural fusion material research, for Ni-58,Ni-60 target nuclei have been calculated by the TALYS 1.6 code at 14.8 MeV neutron incident energy and compared with available experimental data in EXFOR library. While the compound nucleus formation process contribution was found as dominant in the emission of proton and alpha particles, pre-equilibrium contribution was existed in the deuteron emission and the direct reaction contribution also was seen as dominant in higher particle emission energies. Penetrating distance and stopping powers also have been calculated for the alphas, deuterons and protons in Ni-58,Ni-60 using GEANT4 code and compared with previous works of Cr-50,Cr-52 and Ti-46,Ti-48.
