10Abstract
The reaction nu /sub mu /e to nu /sub mu /e 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 64000 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)(X)U(1) model for current values of sin/sup 2/ Theta /sub w/. 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. (10 refs)
