7Abstract
A sample of 1 450 000 interactions with shower energy larger than 2 GeV has been observed in a fine-grain calorimeter exposed to the CERN SPS wide-band antineutrino beam. Among these, 72+/-16 events can be attributed to the neutrino-electron interaction and lead to a value of sin2θ=0.29+/-0.05 (stat.) corresponding to a cross section for the reaction νμe -->νμe of (1.70+/-0.33)×10-42 Eν (cm2/GeV). The systematic error, due to the uncertainties in the knowledge of the antineutrino spectrum, of the electron detection efficiency and of the antineutrino-nucleon total cross section, is estimated to be +/-25%
