摘要：
An experiment to measure the polarization of muons from Kμ30 decay was carried out at the Bevatron with counter techniques. All three components of the polarization were measured. The time-reversal-violating component transverse to the decay plane was found to be PTc.m.=-0.005±0.019, which is consistent with T invariance. The result for the form-factor ratio ξf-f+ was Reξ=-1.81-0.26+0.50, Imξ=-0.02±0.08, Arg (ξ)-π=(0.6±2. 6)°, if ξ is assumed to be independent of q2. If ξ is not too strongly dependent on q2, this result still holds true for ξ at q2≅2.65mπ2, the average q2 selected by our apparatus. © 1969 The American Physical Society.
