The KARMEN experiment uses the reaction 12C(\nu_e,e-)12N to measure theenergy distribution of \nu_e emitted in muon decay at rest. The \nu_e analog\omega_l of the famous Michel parameter \rho has been derived from amaximum-likelihood analysis of events near the kinematic end point, E_max. Theresult, \omega_l = (2.7^{+3.8}_{-3.3}\pm 3.1) * 10^{-2}, is in good agreementwith the standard model prediction \omega_l= 0. We deduce a 90% confidenceupper limit of \omega_l <= 0.113, which corresponds to a limit of |g^S_RL + 2g^T_RL| <= 0.78 on the interference term between scalar and tensor couplingconstants.Comment: 11 pages including 3 figures, submitted to Phys.
