摘要：

The reaction νμe → νμe has been investigated in the bubble chamber Gargamelle exposed to the wide-band neutrino beam of the CERN SPS. Nine electron candidates of which 0.5 are expected to be background, were found in a total statistics available of 64 000 charged current neutrino events. Results are given in terms of vector and axial vector coupling constants. The present results agree with the standard SU(2) ⊗ U(1) model for current values of sin2θw. A critical comparison is made with the previous result based on statistics which were smaller by a factor 2.6 and which led to a rather higher cross section. © 1979.
