The neutrino process and neutrino r-process

Almost all of the 3 · 1053 ergs released in a core-collapse supernova is carried off by the neutrinos emitted from the cooling neutron star. These neutrinos can excite nuclei in the mantle of the star by their neutral and charged current reactions, leading to the spallation of nucleonsa and α-particles and the production of new daughter nuclei, I will describe rather detailed network calculations that suggest this ''neutrino process'' is an important nucleosynthesis mechanisms that may be responsible for the galactic abundances of 7Li, 11B, 19F, 138La, 180Ta, and a number of other nuclei. I also discuss the possibility of an r-process in the He zone of a low-Z progenitor that could be driven, in part, by neutrinos
