Two-loop virtual light-by-light scattering corrections to the bound-electron factor
V. Debierre, B. Sikora, H. Cakir +4
A critical set of two-loop QED corrections to the factor of hydrogenlike ions is calculated without expansion in the nuclear binding field. These corrections are due to the pol…
Improved access to the fine-structure constant with the simplest atomic systems
H. Cakir, N. S. Oreshkina, I. A. Valuev +4
A means to extract the fine-structure constant from precision spectroscopic data on one-electron ions is presented. We show that in an appropriately weighted difference of the…
Detection of metastable electronic states by Penning trap mass spectrometry
Rima Xenia Schüssler, Hendrik Bekker, Martin Braß +19
State-of-the-art optical clocks achieve fractional precisions of and below using ensembles of atoms in optical lattices or individual ions in radio-frequency traps. Prom…
QED corrections to the factor of Li- and B-like ions
H. Cakir, V. A. Yerokhin, N. S. Oreshkina +4
QED corrections to the factor of Li-like and B-like ions in a wide range of nuclear charges are presented. Many-electron contributions as well as radiative effects on the one-l…
