The $\nu$ process in the light of an improved understanding of supernova neutrino spectra

Understand

We study the neutrino-induced production of nuclides in explosive supernova nucleosynthesis for progenitor stars with solar metallicity including neutrino nucleus reactions for all nuclei with charge numbers $Z < 76$ with average neutrino energies in agreement with modern Supernova simulations.

• Considering progenitors with initial main sequence masses between 13~M$_\odot$ and 30~M$_\odot$, we find a significant production of $^{11}$B, $^{138}$La, and $^{180}$Ta by neutrino nucleosynthesis, despite the significantly reduced neutrino energies.
• The production of $^{19}$F turns out to be more sensitive to the progenitor mass and structure than to the $\nu$ process.
• With our complete set of cross sections we have identified effects of the $\nu$~process on several stable nuclei including $^{33}$S, $^{40}$Ar, $^{41}$K, $^{59}$Co, and $^{113}$In at the 10\% level.
