Charge radii of exotic neon and magnesium isotopes

SJ Novario, G Hagen, GR Jansen, T Papenbrock - Physical Review C, 2020 - APS
We compute the charge radii and ground-state energies of even-mass neon and
magnesium isotopes from neutron number N= 8 to the dripline. Our calculations are based …

atomic hydrogen with similar measurements made in atomic deuterium on the search for …

Probing new physics using Rydberg states of atomic hydrogen

MPA Jones, RM Potvliege, M Spannowsky - Physical Review Research, 2020 - APS
We consider the role of high-lying Rydberg states of simple atomic systems such as H 1 in
setting constraints on physics beyond the standard model. We obtain highly accurate bound …

Nuclear charge radii of Na isotopes: Interplay of atomic and nuclear theory

B Ohayon, RFG Ruiz, ZH Sun, G Hagen, T Papenbrock… - Physical Review C, 2022 - APS
The accuracy of atomic theory calculations limits the extraction of nuclear charge radii from
isotope shift measurements of odd-proton nuclei. For Na isotopes, though precise …
