Abstract: A measurement of the transverse mu (+) polarization, P-T, in K+ --> pi (0)mu (+)nu decay was performed using stopped kaons. For 1996-1997 data the results are P-T = -0.0042 +/- 0.0049(stat) +/- 0.0009(syst) and Im(xi) = -0.013 +/- 0.016(stat)+/- 0.003(syst), where Im(xi) is T-violating physics parameter.
