p-Process simulations with a modified reaction library

Abstract

We have performed p-process simulations with the most recent stellar (n, gamma) cross sections from the Karlsruhe Astrophysical Database of Nucleosynthesis in Stars project (version v0.2, http://nuclear-astrophysics.fzk.de/kadonis). The simulations were carried out with a parametrized supernova type II shock front model ('gamma-process') of a 25 solar mass star and compared to recently published results. A decrease in the normalized overproduction factor could be attributed to lower cross sections of a significant fraction of seed nuclei located in Bi and Pb regions around the N = 126 shell closure.
