✦ Synopsis

The weak interaction rates in stellar environments are computed for p f -shell nuclei in the mass range A = 45-65 using large-scale shell-model calculations. The calculated capture and decay rates take into consideration the latest experimental energy levels and log f t-values. The rates are tabulated at the same grid points of density and temperature as those used by Fuller, Fowler, and Newman for densities ρY e = 10-10 11 g/cm 3 and temperatures T = 10 7 -10 11 K, and hence are relevant for both types of supernovae (Type Ia and Type II). Effective f t values for capture rates and average neutrino (antineutrino) energies are also given to facilitate the use of interpolated rates in stellar evolution codes.
