| 内容記述 | We investigate the nuclear abundances uniquely produced from the neutrino neutrino-process in super-nova (SN) explosion. For the first time, we have calculated the neutrino propagation including both its modification by neutrino-self-interaction (neutrino-SI) near the neutrino-sphere and the Mikheyev-Smirnov-Wolfenstein (MSW) mixing in the outer layers. We compute the neutirno-induced nucleosynthesis of 7Li, 11B, 92Nb, 98Tc, 138La, and 180Ta. Near to the neutirno-sphere, the neutrino-density is very high neutirno-SI becomes important. The interaction effect on the neutirno-process is calculated by solving the evolution equation for the neutirno-density matrix with a collision term estimated in the mean field approximation as well as the MSW (neutrino matter oscillations) in the outer layers of the SN. The light element abundances turn out to be increased by the MSW effect, but the neutirno-SI suppresses the MSW effect in the inverted hierarchy scheme. As a result, the ratio of 7Li/11B becomes lower than that of the normal hierarchy, which is consistent with more recent analysis of the meteoritic ratio. |
