摘要：
The neutrino-induced nucleosynthesis (nu process) in supernova explosions of massive stars of solar metallicity with initial main sequence masses between 15 and 40 M-circle dot 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. process is found to contribute still significantly to the production of the nuclei Li-7, B-11, F-19, La-138 and Ta-180, even though the total yields for those nuclei are reduced. Furthermore we study in detail contributions of the. process to the production of radioactive isotopes Al-26, Na-22 and confirm the production of Nb-92 and Tc-98.
