Because of the low entropy of the cores of massive stars, and the resulting dominance of heavy nuclei over free nucleons, the dynamics of stellar core collapse is strongly dependent on nuclear electron and neutrino capture, primarily on nuclei with masses larger than 60. In prior simulations of core collapse, electron and neutrino captures on these nuclei have been treated in a highly parameterized fashion, if not ignored. Recent advances in nuclear structure theory have allowed a more realistic treatment to be developed. With this new treatment, electron and neutrino captures on heavy nuclei dominate throughout collapse, producing significant changes in the dynamics of core collapse, bounce and the stalling of the shock. We will also discuss the sensitivity of these findings to the values of the best currently available weak reaction rates, as well as the possibility of measurements which may better constrain these values.
