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