Calculation of nuclear-spin-dependent parity nonconservation in s-d transitions of Ba+, Yb+, and Ra+ ions

We use correlation potential and many-body perturbation theory techniques to calculate spin-independent and nuclear-spin-dependent parts of the parity nonconserving amplitudes of the transitions between the 6s(1/2) ground state and the 5d(3/2) excited state of Ba+ and Yb+ and between the 7s(1/2) ground state and the 6d(3/2) excited state of Ra+. The results are presented in a form convenient for the extracting of the constants of nuclear-spin-dependent interaction (such as, e. g., anapole moment) from the measurements.
