给出了张量弱耦合常数的T破坏(时间反转)部分的可能存在的改进的上限。分析了以往测量的He-6核β衰变中的电子-中微子方向关联对T破坏耦合的敏感性。分析的结果是在以前破坏T的张量耦合的β衰变极限的背景下提出的，并与精密电偶极矩实验中的一些类似的极限进行了比较。
Improved upper limits are derived on the possible existence of the T-violating (time-reversal) part of the tensor weak coupling constants, C T and C T′. The previous measurements of the electron-neutrino directional correlation in the nuclear beta decay of He 6 are analyzed for sensitivity to T-violating couplings. The results of the analysis are presented in the context of previous beta decay limits on T-violating tensor couplings and compared to somewhat similar limits from precision electric dipole moment experiments.
