Radiative proton capture cross sections in the mass range $40-55$

Abstract

Proton capture cross sections in the energy range of astrophysical interest for mass region 40-54 have been calculated in the Hauser-Feshbach formalism with reaction code TALYS1.6. The density dependent M3Y effective nucleon-nucleon interaction folded with target radial matter densities from relativistic mean field approach is used to obtain the semimicroscopic optical potential. A definite normalization of potential well depths has been used over the entire mass region. The (p, γ) rates of some reactions, important in the astrophysical scenario, are calculated using the potential in the relevant mass region.
