Manifestation of the Nuclear Anapole Moment in M1 Transitions in Thallium

Abstract

We calculate nuclear spin-dependent parity non-conserving $E1$-amplitudes for optical transition $6p_{1/2,F}->6p_{3/2,F^{\prime }}$ and for hyperfine transition $6p_{1/2,F}->6p_{1/2,F^{\prime }}$ in Tl. Experimental limit on the former amplitude placed by Vetter et al. [PRL, 74, 2658 (1995)] corresponds to the anapole moment constant ${\kappa }_a=-0.26\pm 0.27$. Experiment on the hyperfine transition can give direct measurement of the spin-dependent amplitude, because spin-independent amplitude turns to zero.
