Abstract

The neutrino-induced nuclear transition C12(νe,e)12N (g.s.) has been observed with a 15-ton fine-grained tracking detector. The exclusive final state is identified by both an electron track and the positron decay of the N12. From the observation of 181±17 C12(νe,e)12N (g.s.) events with subsequent positron decays the flux-averaged cross section, equivalent to the cross section for 35.0-MeV neutrinos, is [1.05±0.10(stat)±0.10(syst)]×1041 cm2. This result is in good agreement with recent calculations.
