Neutrino-induced nucleosynthesis as a result of mixing between the He and C-O-Ne shells in core-collapse supernova

The nucleosynthesis yields from neutrino-induced spallation of 4He are calculated in case of penetration of some 4He into the carbon-oxygen-neon shell. The neutrino contribution to creation of the weak r-process component becomes noticeable in case 4He is dragged down at radii R < 10^9 cm.
