Abstract: |
We studied the supernova nucleosynthesis induced by neutrino interactions
and found that several isotopes of rare elements like
7Li, 11B, 138La, 180Ta and many others are predominantly
produced by the neutrino-process in core-collapse supernovae.
These isotopes are strongly affected by the neutrino flavor oscillation
due to the MSW (Mikheyev-Smirnov-Wolfenstein) effect.
We here propose a new novel method to determine the unknown neutrino oscillation parameters,
θ13 and mass hierarchy simultaneously from the supernova neutrino-process,
combined with the r-process for heavy-element synthsis and the Galactic chemical evolution on light nuclei. |
