Abstract

A measurement of the muon-neutrino carbon charged-current cross section, C12(,-)X, was performed using the in-flight pion-decay neutrino source at the LAMPF accelerator. At an average interacting neutrino energy of 202 MeV an inclusive cross section of (15.9 2.6 3.7)×10-39 cm2 was measured. This value is in best agreement with the Fermi-gas model and is in disagreement with a previous experiment and subsequent calculations that yielded substantially lower cross sections. However, the muon energy spectrum shows a marked depletion of events at high energies compared to the Fermi-gas model. From a small sample of events in which the final-state nucleus was in the ground state of N12, a cross section for the reaction C12(,-)12N(g.s.) of (1.7 0.8 0.3)×10-39 cm2 or about 11 5 % of the total event rate was obtained.
