Abstract
Updated stellar rates for the reactions ${}^{56}\mathrm{Ni}(p,\ensuremath{\gamma}{)}^{57}\mathrm{Cu}$ and ${}^{57}\mathrm{Cu}(p,\ensuremath{\gamma}{)}^{58}\mathrm{Zn}$ are calculated by using all available experimental information as well as input data from the nuclear shell model. We calculated Coulomb and Thomas-Ehrmann shifts to obtain the unknown excitation energies and the spin/parity assignments of ${}^{58}\mathrm{Zn}.$ The astrophysical consequences are discussed.
