Muon-neutrino and -antineutrino scattering off electrons was detected in a 19-ton Al spark chamber, exposed tothe wide-band v (v-bar) beam from the CERN proton synchrotron. The background was determined experimentally. 11 (10) genuine v/sub ..mu../- (v-bar/sub ..mu../-) e scattering events were found. The respective cross sections are (1.1 +- 0.6) x 10/sup -42/ (E/sub v//GeV) cm/sup 2/ and (2.2 +- 1.0) x 10/sup -42/(E/sub v//GeV) cm/sup 2/. The analysis excludes a pure V-A interaction, and makes a pure V or A theory improbable. The data agree well with the Salam-Weinberg model and sin/sup 2/theta/sub w/ = 0.35 +- 0.08.
