Charged current scattering of νμ, on 12C has been studied using a π+ decay-in-flight νμ beam at the Los Alamos Neutron Science Center. A sample of 66.9±9.1 events satisfying criteria for the exclusive reaction 12 C(νμ,μ-)12Ng.s. was obtained using a large liquid scintillator neutrino detector. The observed flux-averaged cross section (5.6±0.8±1.0) × 10-41 cm2 agrees well with reliable theoretical expectations. A measurement was also obtained for the inclusive cross section to all accessible 12N states 12C(νμ,μ-)X. This flux-averaged cross section is (10.6±0.3±1.8) × 10-40 cm2 which is lower than present theoretical calculations.
