Double Differential Alpha, Proton and Deuteron Emission Cross Section Calculations for the Structural Fusion Materials 46,48Ti

Abstract

Double differential light charged particle emission cross section is a fundamental value to determine nuclear heating and material damages in structural fusion material development. In this study, double differential alpha, proton and deuteron emission cross sections for 46Ti and 48Ti target nuclei have been calculated by the TALYS 1.6 code at 15 MeV incident neutron energy. The light charged particles are emitted due to mainly three different processes—compound, direct and pre-equilibrium. The compound nucleus formation process dominates the emission of light charged particle up to 8 MeV emission energy. Pre-equilibrium and direct reaction contribution become dominant in higher particle emission energies. The calculated double differential cross sections have been compared with the available experimental data taken from the literature.
