摘要：

A search for T-violating transverse muon polarization (P-T(T)T() in the K+0m+n decay was performed using kaon decays at rest. A new improved value P)=-0.00170.0023(stat)0.0011(syst) was obtained giving an upper limit P<0.0050. The T-violation parameter was determined to be Imx=-0.00530.0071(stat)0.0036(syst) giving an upper limit Imx<0.016.
