Description
Neutrino-nucleus reaction cross sections relevant to supernova neutrino detection and nucleosynthesis are evaluated for $^{12}$C, $^{13}$C, $^{16}$O, $^{40}$Ar and $^{56}$Ni with new shell-model Hamiltonians. Cross sections for various gamma and particle emission channels as well as for coherent scattering are obtained for $^{12}$C, $^{13}$C and $^{16}$O. The updated cross sections are compared with available experimental data as well as previous calculations. Advantage of using light targets for coherent scattering is discussed.
Charged-current cross sections folded over neutrino spectra with and without the neutrino oscillations are compared to each other to see how they are sensitive to the MSW and/or collective neutrino oscillation effects.
We also discuss electron-capture rates for supernova explosions and evolution of stars updated with new shell-model Hamiltonians for $sd$- and $pf$-shells. Evaluations of the rates for two-major shells such as $sd$-$pf$ and $pf$-$g$ shells are also in progress.
