Abstract

The neutrino-induced nucleosynthesis (ν process) in supernova explosions of massive stars of solar metallicity with initial main sequence masses between 15 and 40 M_Ȯ has been studied. A new extensive set of neutrino-nucleus cross-sections for all the nuclei included in the reaction network is used and the average neutrino energies are reduced to agree with modern supernova simulations. Despite these changes the ν process is found to contribute still significantly to the production of the nuclei ⁷Li, ¹¹B, ¹⁹F, ¹³⁸La and ¹⁸⁰Ta, even though the total yields for those nuclei are reduced. Furthermore we study in detail contributions of the ν process to the production of radioactive isotopes ²⁶Al, ²²Na and confirm the production of ⁹²Nb and ⁹⁸Tc.
