Proton cross section for Th-232

Abstract

In this research, the cross-sections for proton-induced reactions on Th-232 nuclei evaluated for produce radioisotopes like Ac-225 (t_1/2 =10 d), Th-227 (t_1/2 =18.7d), Pa-231 (t_1/2 =32,760 y) and Pa-232 (t_1/2 =1.31 d).  Experimental data obtained from the EXFOR library, which affiliated with (IAEA) for nuclear reactions (p,x), (p,n) and (p,2n) for energy range (6-194) MeV. Theoretical study conducted to calculate the stopping power using Ziegler equations in the range of energy (6-93) MeV. A program for evaluating cross-sections, yield, and stopping power was developed using MATLAB -2013 in the present work.
