We study the neutrino-induced production of nuclides in explosive supernova
nucleosynthesis for progenitor stars with solar metallicity and initial main
sequence masses between 15 M⊙ and 40 M⊙. We improve previous
investigations i) by using a global set of partial differential cross sections
for neutrino-induced charged- and neutral-current reactions on nuclei with
charge numbers Z<76 and ii) by considering modern supernova neutrino
spectra which have substantially lower average energies compared to those
previously adopted in neutrino nucleosynthesis studies. We confirm the
production of 7Li, 11B, 138La, and 180Ta by neutrino
nucleosynthesis, albeit at slightly smaller abundances due to the changed
neutrino spectra. We find that for stars with a mass smaller than 20 M⊙,
19F is produced mainly by explosive nucleosynthesis while for higher mass
stars it is produced by the ν process. We also find that neutrino-induced
reactions, either directly or indirectly by providing an enhanced abundance of
light particles, noticeably contribute to the production of the radioactive
nuclides 22Na and 26Al. Both nuclei are prime candidates for
gamma-ray astronomy. Other prime targets, 44Ti and 60Fe, however, are
insignificantly produced by neutrino-induced reactions. We also find a large
increase in the production of the long-lived nuclei 92Nb and 98Tc due
to charged-current neutrino capture.Comment: 6 pages, 2 figures, 2 table
