Sensitivity to New Physics of Isotope Shift Studies using the Coronal Lines of Highly Charged Calcium Ions

Nils-Holger Rehbehn, Michael K. Rosner, Hendrik Bekker +8

Promising searches for new physics beyond the current Standard Model (SM) of particle physics are feasible through isotope-shift spectroscopy, which is sensitive to a hypothetical…

Nuclear polarization effects in atoms and ions

V. V. Flambaum, I. B. Samsonov, H. B. Tran Tan +1

In heavy atoms and ions, nuclear structure effects are significantly enhanced due to the overlap of the electron wave functions with the nucleus. This overlap rapidly increases wit…
