An improved search for a T-violating transverse muon polarization (PT) in K+ → π0μ+ν decay was performed using kaon decays at rest. By means of this method, PT was extracted with small systematic errors, PT = −0.0042±0.0049(stat)±0.0009(syst), and the T-violation parameter was determined to be Im ξ = −0.013±0.016(stat) ±0.003(syst).
