Calculation of strongly forbidden M1 transitions and g-factor anomalies in atoms considered for parity-nonconservation measurements

We calculate magnetic dipole transition amplitudes in s - s and s - d transitions of Rb, Cs, Ba+, Fr, Ra+, Yb+, Ac2+ and Th3+. These transitions were used or considered to be used for parity-nonconservation (PNC) measurements. We also calculate the magnetic g-factor anomalies for a selection of states, along with electric quadrupole transition amplitudes for s - d transitions in these systems.
