High-precision Penning-trap spectroscopy of the ground-state spin structure of HD+
Charlotte M. König, Matthew Bohman, Fabian HeiÃe +10
We present high-precision spectroscopy of the ground-state hyperfine structure of HD at 4~T. We determine the bound-electron factor, $g_{e,\mathrm{bound}} = -2.002\,278\,54…

Testing inter-electronic interaction in lithium-like tin
Jonathan Morgner, Vladimir A. Yerokhin, Charlotte M. Konig +9
Magnetic moments of bound-electron systems are a sensitive tool for testing fundamental interactions. factors of lithium-like ions have been rigorously studied in recent years,…

Factor of Boron-like Tin
J. Morgner, B. Tu, M. Moretti +10
In the ALPHATRAP experiment, the factor of boron-like has been measured with a parts-per-billion uncertainty. This is the first high-precision m…
