Abstract

Heavy nuclei abundances in the universe are not attributed to normal stellar burning processes. Nearly all are thought to be a result of the astrophysical r- and s- processes. Thirty-five remaining nuclei cannot be produced through b-decay and consequently are not a result of neutron capture. These p-nuclei are likely due to ?-induced reactions on heavier, stable nuclei in shock fronts of type II supernovae. They could also be the result of deflagration flame fronts in type I supernovae or O-Ne burning zones of massive stars. Regardless of the p-process site, understanding the processes responsible for these p-nuclei are heavily dependent their nuclear properties.
