Charged current reactions of ve on 12C have been studied using a μ+ decay-at-rest ve beam at the Los Alamos Neutron Science Center. The cross section for the exclusive reaction 12C(ve,e-)12Ng.s. was measured to be (8.9 ± 0.3 ± 0.9) × 10-42 cm2. The observed energy dependence of the cross section and angular distribution of the outgoing electron agree well with theoretical expectations. Measurements are also presented for inclusive transitions to 12N excited states, 12C(ve ,e-)12N* and compared with theoretical expectations. The measured cross section, (4.3 ± 0.4 ± 0.6) × 10-42 cm2, is somewhat lower than previous measurements and than a continuum random phase approximation calculation. It is in better agreement with a recent shell model calculation.
