Parity non-conservation has been observed in the inelastic scattering of longitudinally polarized electrons from an unpolarized deuterium target at 19.4 and 22.2 GeV. We find an asymmetry A= (sigma/sub R/-sigma/sub L/)/(sigma/sub R/+sigma/sub L/) =-9.5 +- 1.6) x 10/sup -5/ Q/sup 2/, Q/sup 2/ in (GeV/c)/sup 2/, for values of Q near 1.4. The statistical and asystematic errors are each about 9 percent of the measured asymmetry. This result is consistent with predictions from the standard Weinberg-Salam SU(2) x U(1) model. Using the simple quark-parton model of the nucleon, we obtain Sin/sup 2/theta/sub W/=0.20 +- 0.03.
