摘要：

The transverse polarization in a plane perpendicular to the nuclear spin has been measured for electrons emitted in the beta decay of polarized Li-8 nuclei. The amplitude R of the time-reversal-violating triple correlation between nuclear spin, momentum, and spin of the electron has been determined. Our result, R = 0.004 +/- 0.014, is consistent with time-reversal invariance and provides a first direct limit on the imaginary charged weak tensor interaction -0.03 < Im (C(T) + C(T)'/C(A) < 0.05.
