Abstract
We consider the conditions for the r process to proceed when a shock wave p asses through the helium shell of a collapsing Type II supernova of mass 10 -15M(.). We analyze the effect of reactions with protons and alpha particle s on the r process when the helium shell is irradiated by a neutrino flux a nd when the parametrically specified post-shock temperature increases. The sources of neutrons and protons are the reactions of inelastic scattering o f muon and tau neutrinos and antineutrinos by helium nuclei which have been previously discussed in detail.
