Abstract

We have studied detailed nucleosynthesis in the shocked surface layers of an oxygen-neon-magnesium corecollapse supernova with an eye to determining whether the conditions are suitable for r-process nucleosynthesis. We find no such conditions in an unmodified model, but do find overproduction of N = 50 nuclei (previously seen in early neutron-rich neutrino winds) in amounts that, if ejected, would pose serious problems for Galactic chemical evolution.
