We study the elastic scattering of neutrinos and antineutrinos on nucleons in the Weinberg-Salam model of the neutral current. In particular, we incorporate into our calculation the experimental cuts relevant to the two recent BNL experiments and also fold in the BNL ..nu.. and anti ..nu.. spectra. Sensitivity of the calculation to the changes in the axial-vector-meson mass and the Weinberg angle are explored. We conclude that the Weinberg-Salam model prediction for R/sub el/ = < sigma (..nu../sub ..mu../ + p ..-->.. ..nu../sub ..mu../ + p) > / < sigma (..nu../sub ..mu../ + n ..-->.. anti ..mu.. + p) > and the differential-cross-section measurements are not inconsistent with the data provided the uncertainty in the mass of the axial-vector meson M/sub A/ is taken into account. Similar predictions are given for anti ..nu..N scattering. (AIP)
