Nuclear Responses for Neutrinos and Mo Observatory of Neutrinos

Abstract

Nuclear responses for neutrinos and neutrino studies in Mo nuclei are briefly reported. Nuclear spin-isospin responses for neutrinos are crucial for neutrino studies in nuclei. Spin-isospin responses for solar neutrinos, supernova neutrinos and neutrinos involved in double-beta decays are discussed. It is of great interest to study neutrino masses and low energy solar neutrinos. It is shown that it is possible to carry out with 100Mo both spectroscopic studies of double-beta decays with the sensitivity of the order of 〈mν〉 ≈ 0.03eV and real-time exclusive studies of the low energy solar neutrinos.
