N2 - Spin-dipole strength in 16O and ν-induced reactions on 16O are studied by shell-model calculations. Charged- and neutral-current reaction cross sections for various particle and γ emission channels as well as the total ones are evaluated with the Hauser-Feshbach statistical method. Nucleosynthesis of 11B and 11C in supernovae through αp emission channels is investigated. Charged-current reaction cross sections induced by supernova ν and their dependence on ν oscillations are discussed for future supernova burst. Neutrino-nucleus reaction cross sections on 20Ne induced by Gamow-Teller and spin-dipole transitions are also investigated. Electron-capture rates for the forbidden transition 20Ne (e-, νe) 20F (2g.s.+) at stellar environments are discussed.
