Rate tables for the weak processes of pf-shell nuclei in stellar environments

The weak interaction rates in stellar environments are computed for pf-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 rhoY(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 1a and Type II). Effective values for capture rates and average neutrino (antineutrino) energies are also given to facilitate the use of interpolated rates in stellar evolution codes. (C) 2001 Academic Press.
