Neutrino induced transitions between the ground states of the A=12 triad

Abstract

Neutrino induced reactions on 12C, an ingredient of liquid scintillators, have been studied in several experiments. We show that for currently available neutrino energies, Eν≤ 300 MeV, calculated exclusive cross sections 12Cg.s.(ν,l)12Ng.s. for both muon and electron neutrinos are essentially model independent, provided the calculations simultaneously describe the rates of several other reactions involving the same states or their isobar analogs. The calculations agree well with the measured cross sections, which can be therefore used to check the normalization of the incident neutrino spectrum and the efficiency of the detector.
