The transverse polarization of muons from the decay K/sup +/..--> pi../sup 0/..mu../sup +/..nu../sub ..mu../ was measured at Brookhaven National Laboratory. Having detected and measured 2.1 x 10/sup 7/ ..mu../sup +/..-->..e/sup +/..nu../sub e/nu-bar/sub ..mu../ decays we found that the T-violating component of muon polarization perpendicular to the K/sup +/ decay plane P/sub n/ = -0.0031 +- 0.0053. Combining this result with our result for K/sub mu3//sup 0/, we obtain as a measure of T- (and therefore CP-) invariance violation Imxi = -0.010 +- 0.019.
