Abstract
The weak neutral current reaction C-12(nu(mu), nu(mu)')C-12 (1(+),1; 15.1 MeV) has been observed for the first time in the KARMEN experimen t. Neutrino events were separated from background using two different analysis methods. The measured cross section sigma(NC) = (3.2 +/- 0.5( stat.) +/- 0.4(syst.)) x 10(-42) cm(2) for monoenergetic nu(mu) from p i(+)-decay at rest is in good agreement with the standard model, the i sovector-axialvector coupling constant of weak hadronic current deduce d from this experiment is \beta\ = 1.11 +/- 0.13.
