Description
Nuclear physics input plays an important role in core-collapse supernova simulation. Nuclear shell model based methods reliably predict the capture rates, however, the feasibility cuts the method short. Earlier we reported on the extension of the pool of hybrid rates to 250 nuclei of pf+gds model space. Here we present even more enlarged pool based on a schematic Fermi-Dirac approximation to the parent nucleus ground state occupation numbers. More than 2500 nuclei with Z=28-70 and N=40-160 are calculated within the schematic hybrid model. The NSE-averaged electron capture rate and the emitted neutrino spectra are calculated. The screening effects are taken into account both in calculation of the nuclear abundances and calculating the capture rates as well as neutrino spectra.
