High Resolution Photoexcitation Measurements Exacerbate the Long-Standing Fe XVII Oscillator Strength Problem
Steffen Kühn, Chintan Shah, José R. Crespo López-Urrutia +29
For more than 40 years, most astrophysical observations and laboratory studies of two key soft x-ray diagnostic transitions, and , in Fe XVII ions found oscillator…
Detection of the orbital crossing and its optical clock transition in Pr
H. Bekker, A. Borschevsky, Z. Harman +5
Recent theoretical works have proposed atomic clocks based on narrow optical transitions in highly charged ions. The most interesting candidates for searches of new physics are tho…
-factor of Boronlike Argon
I. Arapoglou, A. Egl, M. Höcker +15
We have measured the ground-state -factor of boronlike argon with a fractional uncertainty of \SI{1.4e-9}{} with a single ion in the newly developed ALP…
The factor of bound electrons as a test for physics beyond the Standard Model
V. Debierre, C. H. Keitel, Z. Harman
The use of high-precision measurements of the factor of few-electron ions and its isotope shifts is put forward as a probe for physics beyond the Standard Model. The contributi…
