摘要：

Charged current reactions of nu (e) on C-12 have been studied using a mu (+) decay-at-rest nu (e) beam at the Los Alamos Neutron Science Center. The cross section for the exclusive reaction C-12(nu (e), e) N-12(g.s). was measured to be (8.9 +/-0.3 +/-0.9) x 10(-42) cm(2). 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 N-12 excited states, C-12(nu (e), e(-))N-12* and compared with theoretical expectations, The measured cross section, (4.3 +/-0.4 +/-0.6) x 10(-42) cm(2), 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.
