Breit corrections to moderately charged ions in all-orders calculations
Andoni Skoufris, Benjamin M. Roberts
The atomic properties of heavy, moderately-charged ions are important for a wide variety of applications, including precision tests of fundamental physics and for the study and dev…
QED radiative corrections to electric dipole amplitudes in heavy atoms
C. J. Fairhall, B. M. Roberts, J. S. M. Ginges
We use the radiative potential method to perform a detailed study of quantum electrodynamics (QED) radiative corrections to electric dipole (E1) transition amplitudes in heavy alka…
Experimental and theoretical study of dynamic polarizabilities in the - clock transition in rubidium-87 and determination of E1 matrix elements
Rhona Hamilton, Benjamin M. Roberts, Sarah K. Scholten +4
The interaction between light and an atom causes perturbations in the atom's energy levels, known as the light-shift. These light-shifts are a key source of inaccuracy in atomic cl…
Electric dipole transition amplitudes for atoms and ions with one valence electron
B. M. Roberts, C. J. Fairhall, J. S. M. Ginges
Motivated by recent measurements for several alkali-metal atoms and alkali-metal-like ions, we perform a detailed study of electric dipole (E1) transition amplitudes in K, Ca+, Rb,…
The Bohr-Weisskopf effect: from hydrogenlike-ion experiments to heavy-atom calculations of the hyperfine structure
B. M. Roberts, P. G. Ranclaud, J. S. M. Ginges
In this paper we study the influence of electron screening on the Bohr-Weisskopf (BW) effect in many-electron atoms. The BW effect gives the finite-nucleus magnetization contributi…
Comment on "New physics constraints from atomic parity violation in 133-Cs"
B. M. Roberts, J. S. M. Ginges
In a recent Letter [B. K. Sahoo, B. P. Das, and H. Spiesberger, Phys. Rev. D 103, L111303 (2021)], a calculation of the parity violating 6S-7S E1 amplitude in Cs is reported, claim…
