Contribution

It analyzes the hyperfine mixing effects on forbidden transitions in Yb, highlighting their significance for parity violation measurements.

Findings

Hyperfine mixing enables E2 transition channels in Yb.

Differences in transition amplitudes depend on F-sublevels.

Implications for nuclear-spin-dependent parity violation detection.

Abstract

Parity violation experiment in Yb is made on the strongly forbidden M1 transition 6s^2 1S0 \to 5d6s 3D1. The hyperfine mixing of the 5d6s 3D1 and 5d6s 3D2 levels opens E2 channel, whose amplitude differs for F-sublevels of the 3D1 level. This effect may be important for the experimental search for the nuclear-spin-dependent parity violation effects predominantly caused by the nuclear anapole moment.
