Neutrino-nucleus reactions on ${}^{16}$O based on new shell-model Hamiltonians

Abstract

Neutrino-induced reactions on ${}^{16}$O are investigated by shell-model calculaions with new shell-model Hamiltonians, which can describe well the structure of $p$-shell and $p$-$sd$ shell nuclei. Distribution of the spin-dipole strengths in ${}^{16}$O, which give major contributions to the $\nu$-${}^{16}$O reaction cross sections, is studied with the new Hamiltonians. Muon-capture reaction rates on ${}^{16}$O are also studied to discuss the quenching of the axial-vector coupling in nuclear medium. Charged-current and neutral-current reaction cross sections are evaluated in various particle and $\gamma$ emission channels as well as the total ones at neutrino energies up to $E_{\nu }\approx$ 100 MeV. Branching ratios for the various channels are obtained by the Hauser-Feshbach statistical model calculations, and partial cross sections for single- and multi-particle emission channels are evaluated. The cross sections updated are compared with previous continuum random phase approximation (CRPA) calculations. Effects of multi-particle emission channels on nucleosynthesis in core-collapse supernova (SN) explosions are investigated. Inclusion of $\alpha$p emission channels is found to lead to an enhancement of production yields of ${}^{11}$B and ${}^{11}$C through ${}^{16}$O ($\nu$, $\nu$' $\alpha$p) ${}^{11}$B and ${}^{16}$O ($\nu$, e${}^{-}$ $\alpha$p) ${}^{11}$C reactions, respectively.
