Description
Summary:Development of large mass detectors for low-energy neutrinos and dark matter may allow supernova detection via neutrino-nucleus elastic scattering. Coherent elastic neutrino-nucleus interaction allows quite large cross sections in the case of neutron-rich targets, which can be exploited in detecting earth and sky neutrinos by measuring nuclear recoils. In this work, the neutrino-induced recoil events are calculated in the neutrino-nucleus coherent scattering. The differential cross section is folded with a neutrino energy spectrum in the Fermi-Dirac model. The calculations were applied to several targets from 4He to 208Pb. An elastic scattering neutrino detector could observe a significant number of events per ton from a galactic supernova at 10 kpc (3.1 × 1020 m). This large yield arises because of the very large coherent cross section and the sensitivity to all flavors of neutrinos and antineutrinos.
