摘要：

We are reporting on a determination of neutral current coupling constants from a study of differential cross sections of muon(anti)neutrino-electron scattering. The results were obtained with the CHARM-II detector which was exposed to the CERN wide band neutrino beam in the years 1987-1990. A total of about 2100 ve and 2200 veBAR scattering events were observed. From a comparison between the data and predicted event distributions, the effective vector and axial-vector neutral current coupling constants of the electron were determined to be g(V)e = -0.025 +/- 0.019 and g(A)e = -0.503 +/- 0.018.
