• We discuss the effects of Majorana neutrino resonant spin-flavor precession on models for the heavy element nucleosynthesis and the explosion dynamics of Type II supernovae. We point out that for plausible ranges of neutrino magnetic moments and proto-neutron star magnetic fields spin-flavor conversion of ν_γ( or ν_μ) with a cosmologically significant mass(1-100 eV) into a light ν^^-_e could lead to enhanced neutron excess in neutrino-heated supernova ejecta. This may be beneficial for models of γ-process nucleosynthesis associated with Type II supernovae. Spin-flavor conversion of neutrinos with these masses at earlier epoch lead to an increased shock reheating rate and, concomitantly, a larger supernova explosion energy.
