$p$-Process simulations with a modified reaction library

Astrophysics 2010-11-23 v1 Nuclear Experiment

Abstract

We have performed pp-process simulations with the most recent stellar (n,γ)(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 (``γ\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 the Bi and Pb region around the NN=126 shell closure.
