  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 B11, F19, La138,
and Ta180. The production of these isotopes places limits on neutrino spectrum
and oscialltions.
