Studying low-energy astrophysical neutrinos with neutrino nucleus cross-section calculations and beta beam neutrino spectra

摘要

We first calculate total neutrino-nucleus cross-sections for the reactions ~(66)Zn(~(ν?,ν?′))66Zn ~* and ~(130)Te(~(ν?,ν?′)) ~(130)Te* within the context of the quasiparticle random phase approximation. The isotopes ~(66)Zn and ~(130)Te are contents of the COBRA double beta decay detector at Gran Sasso. We then use synthetic low-energy beta-beam antineutrino spectra, originating from boosted β- radioactive 6He ions for the interpretation of various SN-neutrino signals.
