摘要：

New evaluations of neutrino-nucleus reaction rates are made for fp-shell and light p-shell nuclei as well as (4)He based on new shell model Hamiltonians, which give good account of spin dependent properties such as Gamow-Teller (GT) transitions and magnetic moments in the nuclei. The reaction cross sections in light nuclei are found to be enhanced compared with those obtained by conventional Hamiltonians and previous calculations. The production yields of (7)Li and (11)B during supernova explosions are found to be enhanced. The GT strengths in Fe and Ni isotopes are found to be more fragmented than those by conventional Hamiltonians. In particular, this results in an enhancement of the neutrino-induced cross section on (56)Ni for proton emission channel, and also an enhanced production yield of (55)Mn in population III stars. Electron capture rates on Fe and Ni isotopes in astrophysical environment are studied, and they are found to be reduced systematically compared with those by conventional Hamiltonians.
