摘要：

Parity nonconservation is observed in the 6P122-7P122 transition in thallium. Absorption of circularly polarized 293-nm photons by 6P122 atoms in an E field results in polarization of the 7P122 state through interference of Stark E1 amplitudes with M1 and parity-nonconserving E1 amplitudes M and Ep. Detection of this polarization yields the circular dichroism δ=+(5.2±2.4)×10-3, which agrees in sign and magnitude with theoretical estimates based on the Weinberg-Salam model. © 1979 The American Physical Society.
