Proton capture reactions in medium-heavy nuclei relevant to p-process nucleosynthesis

Abstract

Cross-section measurements of proton-capture reactions on Molybdenum isotopes have been performed at beam energies from 2.0 to 6.2 MeV. The cross-section data obtained in this work are compared with those predicted by theory. The latter were calculated using the latest version of the TALYS Hauser-Feshbach (HF) theory code [1] (version 1.6). In these calculations, various phenomenological and (semi)microscopic models were used for the nucleon-nucleus and the α-particle-nucleus optical model potential, the nuclear level densities and the γ-ray strength function.
