Neutrino Nucleosynthesis

We study neutrino process nucleosynthesis in massive stars using newly calculated cross sections, an expanded reaction network, and complete and self-consistent models of the progenitor star. We reevaluate the production of light isotopes from abundant progenitors as well as that of rare, heavy, proton-rich isotopes. In particular, new results are given for 11 B, 19 F, 138 La, and 180 Ta. The production of these isotopes places limits on neutrino spectrum and oscialltions.
