Abstract:
The neutrino-nucleus reaction cross sections of 4He and 12C are
evaluated using new shell model Hamiltonians. Branching ratios of
various decay channels are calculated to evaluate the yields of Li,
Be, and B produced through the ν-process in supernova explosions.
The new cross sections enhance the yields of 7Li and 11B produced
during the supernova explosion of a 16.2M☉ star model compared
to the case using the conventional cross sections by about 10%. On the
other hand, the yield of 10B decreases by a factor of 2. The yields
of 6Li, 9Be, and the radioactive nucleus 10Be are found at a
level of ∼10-11M☉. The temperature of νµ,τ - and
ν{bar}µ,τ - neutrinos inferred from the supernova
contribution of 11B in Galactic chemical evolution models is
constrained to the 4.3-6.5MeV range. The increase in the 7Li and
11B yields due to neutrino oscillations is demonstrated with the new
cross sections.
