Hyperfine transitions in He-like ions as a tool for nuclear-spin-dependent parity-nonconservation studies

Abstract:
In this paper a scheme is proposed for measuring nuclear-spin-dependent parity-nonconservation effects in highly charged ions. The idea is to employ circularly polarized laser light for inducing the transition between the level (1s2s)^1S_0 and the hyperfine sublevels of (1s2s)^3S_1 in He-like ions with nonzero nuclear spin. We argue that an interference between the allowed magnetic dipole M1 and the parity-violating electric dipole E1 decay channel leads to an observable asymmetry of order 10^(-7) in the transition cross section, in the atomic range 28 ⩽ Z ⩽ 35. Experimental requirements for asymmetry measurements are discussed in the case of He-like (34)_Se^(77).
