Theoretical characterisation of the barium II and radium II ions
Robin B. Cserveny, Benjamin M. Roberts
Motivated by recent experimental advances, including the ongoing development of an optical atomic clock in singly ionised radium, we perform a detailed theoretical characterisation…

The hyperfine anomaly in mercury and test of the Moskowitz-Lombardi rule
J. Vandeleur, G. Sanamyan, B. M. Roberts +1
The Moskowitz-Lombardi rule gives a simple relation between the magnetic moment of an atomic nucleus and the effect of its radial distribution on the hyperfine structure - the magn…

Vacuum polarization corrections to hyperfine structure in many-electron atoms
J. C. Hasted, C. J. Fairhall, O. R. Smits +2
We perform a theoretical study of vacuum polarization corrections to the hyperfine structure in many-electron atoms. Calculations are performed for systems of interest for precisio…
