Charged-current neutrino-208Pb reactions

Abstract

We present theoretical results on the non flux-averaged ${}^{208}Pb({\nu }_e,e^{-}{)}^{208}Bi$ and ${}^{208}Pb({\nu }_{\mu },{\mu }^{-}{)}^{208}Bi$ reaction cross sections, obtained within the charge-exchange Random-Phase-Approximation. A detailed knowledge of these cross sections is important in different contexts. In particular, it is necessary to assess the possibility of using lead as a detector in future experiments on supernova neutrinos, such as OMNIS and LAND, and eventually detect neutrino oscillation signals by exploiting the spectroscopic properties of ${}^{208}Bi$. We discuss the present status on the theoretical predictions of the reaction cross sections.
