Neutrino-nucleus reactions in terrestrial experiments and astrophysics

We focus on the role and importance of neutrino-nucleus interactions to neutrino detection by terrestrial detector-nuclei and to various processes as well as scattering effects occurring inside the matter of stars (supernova, etc.) that generate the astrophysical neutrino energy spectra. We specifically concentrate on the parameterizations of the supernova neutrino energy distributions and examine the use of the low-energy β -beam spectra, originating from the boosted radioactive nuclei 6He and 18Ne, for such purposes.
