摘要：

The 6s2 S016s5d D13 transition in atomic Yb is proposed for use in the study of atomic parity nonconservation (PNC). This transition is shown to have a very large E1 amplitude arising from PNC: |Im(E1PNC)|1.1×10-9ea0, and also a strongly suppressed M1 amplitude and a moderate Stark-induced amplitude. Extremely high-precision measurements of PNC in Yb appear possible, using experimental techniques of proven utility. Comparison of PNC in the wide range of stable isotopes of Yb may provide a unique test of the standard model of electroweak interactions. © 1995 The American Physical Society.
