We have measured the processe/sup +/e/sup -/..--> mu../sup +/..mu../sup -/ at ..sqrt..s = 29 GeV using the High Resolution Spectrometer at SLAC PEP. The forward-backward charge asymmetry is A/sub mumu/ = -(4.9 +- 1.5 +- 0.5)% based on 5057 events. A subsample of 3488 ..mu../sup +/..mu../sup -/ events in the angular range Vertical BarcosthetaVertical Bar 170 GeV and ..lambda../sub -/>146 GeV at 95% C.L.
