Description

A new shell model Hamiltonian for p-shell nuclei which properly takes into account important roles of spin-isospin interactions is used to obtain cross sections of neutrino-12C reactions induced by decay-at-rest neutrinos as well as supernova neutrinos. Branching ratios to various decay channels are calculated by the Hauser-Feshbach theory. Neutrino-4He reactions are also investigated by using recent shell model Hamiltonians. The reaction cross sections are found to be enhanced for both 12C and 4He compared with previous calculations. As an interesting consequence of this, a possible enhancement of the production yields of light elements, 7Li and 11B, during supernova explosions is pointed out
