摘要：

We applied the quasiparticle random-phase approximation to neutrino reactions on C-12 target. The quasiparticle random-phase approximation (QRPA) has been found to successfully explain the nuclear beta and beta beta decays. To describe neutrino-nucleus reactions, various multipole transitions by weak interactions with finite momentum transfers are added to the Gamow Teller transition in the beta decays. Our results are shown to well reproduce most of experimental data for neutrino reactions on C-12 target. In particular, energy dependence of cross sections for the exclusive reaction, C-12(nu(e), e(-))N-12(g.s(1+)), is discussed in detail by comparing the QRPA calculations to related experimental data.
