Özet
We report our final results from the analysis of the full high statistics sample of events of the reaction nu(mu) + e(-) --> mu(-) + nu(e) collected with the CHARM II detector in the CERN wide-band neutrino beam during the years 1988 to 1991. From a signal of 15 758 +/- 324 inverse muon decay events we derived, in the Born approximation, a value of (16.51 +/- 0.93) x 10(-42) cm(2) GeV-1 for the asymptotic cross section slope sigma/E(n)u, in good agreement with the Standard Model prediction of 17.23 x 10(-42) cm(2) GeV-1. The result constrains the scalar coupling of the electron and the muon to \g(LL)(S)\(2) < 0.475 at 90% CL.
