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 <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. (C) 2001 Academic Press.
