Search for parity violation in deep-inelastic scattering of polarized electrons by unpolarized deuterons

We report on recent asymmetry measurements for inelastic scattering of longitudinally polarized electrons from an unpolarized deuterium target at 19.4 GeV. Using the SLAC 20-GeV/c and 8-GeV/c spectrometers, the helicity-dependent cross-section asymmetries were measured at Q/sup 2/ values of 1.2 and 4.2 GeV/c/sup 2/, and were found to be less than 2 x 10/sup -3/ and 7 x 10/sup -3/, respectively.
