Measurements of the reactions {sup 12}C({nu}{sub e},e{sup {minus}}){sup 12}N{sub g.s.} and {sup 12}C({nu}{sub e},e{sup {minus}}){sup 12}N{sup {asterisk}}

Charged current reactions of {nu}{sub e} on {sup 12}C have been studied using a {mu}{sup +} decay-at-rest {nu}{sub e} beam from the Los Alamos Meson Physics Facility. More than 500 events from the exclusive reaction {sup 12}C({nu}{sub e},e{sup {minus}}){sup 12}N{sub g.s.} were measured in a large Liquid Scintillator Neutrino Detector (LSND). The observed energy dependence of the cross section and the angular distribution of the outgoing electron agree well with theoretical expectations. Measurements are also presented for inclusive transitions to {sup 12}N excited states, {sup 12}C({nu}{sub e},e{sup {minus}}){sup 12}N{sup {asterisk}} and compared with theoretical expectations. Results are consistent with a recent continuum random phase approximation (CRPA) calculation. {copyright} {ital 1997} {ital The American Physical Society}
