    We report final results on electroweak parameters from muon-neutrino electron scattering observed in the CHARM II detector from 1987 till 1991. In total 2677±82 and 2752±88 neutrino-electron scattering events have been detected in the ν and ν-beam, respectively. From the ration of differential cross sections we obtain for the electroweak mixing angle sin2 Θ = 0.2324±0.0083. From the absolute neutrino-electron scattering event rate we determined the effective vector and axial-vector neutral current coupling constants to be gVve = -0.035±0.017 and gAve = -0.503±0.017. © 1994.0SCOPUS: ar.jinfo:eu-repo/semantics/publishe
