[en] The final results from the CHARM II experiment on neutrino-electron scattering and inverse muon decay (IMD) are reported. From the study of the first process the vector and axial-vector coupling constants of the muon neutrino to the electron, g_V^νe, are obtained; the comparison of these results with the LEP measurements allows to test the Standard Model at a scale of Q² ∼0.01 GeV²,to estimate the coupling of the muon neutrino to the Z, and to test the universality of neutrino couplings in neutral current interactions. The study of the inverse muon decay reaction complements the results on muon decay in determining the structure of the charged current coupling of the electron to the muon; a limit on the scalar coupling of these particles is derived.
