The ν process with updated supernova neutrino spectra

As the shock of the supernova explosion ejects the stellar mantle, the material
is subject to shock heating and compression as well as to strong neutrino
irradiation. Neutrino induced reactions on nuclei affect the nucleosynthesis in
the neutrino process (e.g. Woosley et al. 1990) that is likely to be
responsible for the solar abundances of several rare nuclei such as ¹¹B, ¹³⁸La
and ¹⁸⁰Ta. This process also affects the production of radioactive isotopes such as ²⁶Al
and ²²Na.  In particular the neutrino process could provide and explanation for
the Ne-E(L) meteoritic noble gas component (Amari et al. 2009).  For the first
time this process  is studied with time dependent neutrino properties based on
modern supernova simulations. We find that accounting for the time dependence
of the  neutrino luminosities and energies with an extended phase of enhanced
accretion luminosity can be important to explain the solar abundances of ¹¹B
and ¹³⁸La and ¹⁸⁰Ta when other contributions to ¹¹B are taken into account.
