Abstract
The process of electron emission from ∼30 MeV neutrino absorption on carbon, (,N, has been observed. The flux-weighted total cross section for the exclusive neutrino-induced nuclear transition (,N(g.s.) is [1.05±0.10(stat)±0.10(syst)]× . The measured cross section and angular distribution dσ/dΩ are in agreement with theoretical estimates. The inclusive reaction rate, which accounted for the majority of all neutrino interactions observed in this experiment, was determined from a detailed fit of energy and angular distributions for the observed electrons. The inclusive (,)X cross section is measured to be [1.41±0.23(tot)]× . An upper limit for the sum of the (,)XAl(,)X inclusive absorption cross sections is presented.
