Pre-equilibrium and direct-semi-direct model calculations of proton radiative capture excitation functions near A=60

Abstract

Excitation functions of integrated cross section for 2656Fe(p, gamma )2757Co, 2759Co(p, gamma ) 2860Ni, 2858,60,61Ni(p, gamma )2959,61,62Cu, 2963Cu(p, gamma )3064Zn and 3064Zn(p, gamma )3165Ga reactions were calculated using pre-equilibrium-equilibrium capture exciton model and, for comparison, also the direct-semidirect capture model in order to extend the systematic study of the former one in the region of medium-weight nuclei. After the correction of binding energies for pairing within the pre-equilibrium calculation. The results of both models compare relatively well to the available experimental data.
