A muon-spin-rotation technique has been used to place limits on right-handed currents in ..mu../sup +/ decay. The spins of polarized ..mu../sup +/ stopped in metal targets were precessed by 70-G of 110-G transverse fields. The muon-spin-rotation signal amplitude produced by high-momentum decay e/sup +/ emitted near the beam direction implies xiP/sub ..mu../delta/rho>0.9955 and M(W/sub 2/)>370 GeV (90% confidence), where W/sub 2/ is predominantly right-handed gauge boson. The present result combined with our previous spin-held analysis yields xiP/sub ..mu../delta/rho>0.9966 and M(W/sub 2/)>400 GeV.
