Cross Sections of Charged Current Neutrino Scattering off132Xe for the Supernova Detection

Abstract

The total cross sections as well as the neutrino event rates are calculated in the charged current neutrino and antineutrino scattering off132Xe isotope at neutrino energiesEv<100 MeV. Transitions to excited nuclear states are calculated in the framework of quasiparticle random-phase approximation. The contributions from different multipoles are shown for various neutrino energies. Flux-averaged cross sections are obtained by convolving the cross sections with a two-parameter Fermi-Dirac distribution. The flux-averaged cross sections are also calculated using terrestrial neutrino sources based on conventional sources (muon decay at rest) or on low-energy beta-beams.
