Özet

Background: The gamma process in supernova explosions is thought to explain the origin of proton-rich isotopes between Se and Hg, the so-called p nuclei. The majority of the reaction rates for gamma process reaction network studies have to be predicted in Hauser-Feshbach statistical model calculations using global optical potential parametrizations. While the nucleon+nucleus optical potential is fairly well known, for the alpha+nucleus optical potential several different parametrizations exist and large deviations are found between the predictions calculated using different parameter sets.
