Phys. Rev. Lett. 74, 4165–4168 (1995)Parity Nonconservation in the 6s21S0→6s5d3D1 Transition in Atomic YtterbiumReceived 13 December 1994; published in the issue dated 22 May 1995 The 6s21S0→6s5d3D1 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 URL:
