Study of Excitation Functions of (p, n) Reactions for 56Fe and 57Fe Target from Threshold to 30 MeV
The theoretical calculation of the cross section for formation of 56,57co in (p, n) reaction from 56,57Fe target have been studied from reaction threshold to 30 MeV using TALyS-1.4 nuclear model reaction code whereby we have studied major nuclear reaction mechanisms, including direct, pre-equilibrium and compound nuclear reactions. These calculations were carried out by adjusting the effective imaginary potential, level density and shell damping parameters. It is observed that an excellent agreement between the theoretical calculated and experimental data is obtained with minimal effort on parameter fitting. we have also observed that there is significant contribution of pre-equilibrium emission in (p, n) reaction cross-section of 56Fe and 57Fe. The systematic increase in (p, n) cross-sections with increasing neutron number in reactions induced by protons on 56Fe and 57Fe is explained in terms of compound and pre-equilibrium mode.
