Abstract

Charged-current neutrino-nucleus cross sections for 54, 56Fe and 58, 60Ni are calculated and compared using frameworks based on relativistic and Skyrme energy-density functionals and on the shell model. The current theoretical uncertainties in modeling neutrino-nucleus cross sections are assessed in relation to the predicted Gamow-Teller transition strength and available data, to multipole decomposition of the cross sections, and to cross sections averaged over the Michel flux and Fermi- Dirac distribution. By employing different microscopic approaches and models, the decay-at-rest (DAR) neutrino-56Fe cross section and its theoretical uncertainty are estimated to be 〈σ〉th=(258±57)×10−42 cm2, in very good agreement with the experimental value 〈σ〉exp=(256±108±43)×10−42 cm2.
