Özet

Background: The. process in core-collapse 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 has to be predicted in Hauser-Feshbach statistical model calculations. Recent investigations have shown problems in the prediction of alpha widths at astrophysical energies. This impacts the reliability of abundance predictions in the upper mass range of the p nuclei.
