Abstract

The neutrino-induced nucleosynthesis (ν process) in supernova explosions of massive stars of solar metallicity with initial main sequence masses between 13 and 30 M_⊙ has been studied with an analytic explosion model using a new extensive set of neutrino-nucleus cross-sections and spectral properties that agree with modern supernova simulations. The production factors for the nuclei ⁷Li, ¹¹B, ¹⁹F, ¹³⁸La and ¹⁸⁰Ta, are still significantly enhanced but do not reproduce the full solar abundances. We study the possible contribution of the innermost supernova eject to the production of the light elements ⁷Li and ¹¹B with tracer particles based on a 2D supernova simulation of a 12 M_⊙ progenitor and conclude, that a contribution exists but is negligible for the total yield for this explosion model.
