We present here preliminary results on a recent experiment on nu/sub ..mu../ - e/sup -/ elastic scattering. A brief review of the Glashow-Salam-Weinberg theory is given, indicating how the measurement of the total cross section gives rise to an ambiguous solution for sin/sup 2/ THETA/sub w/, and showing how the differential cross section can be used to resolve the ambiguity. The experimental configuration and the extraction of the signal are described. The data are compared with those from our previous experiment, and relevant distributions from the combined data sample are presented. The differential cross section is examined in an attempt to resolve the ambiguity in sin/sup 2/ THETA/sub w/, the lower value of sin/sup 2/ THETA/sub w/ = 0.20 being favored.
