High-precision Penning-trap spectroscopy of the ground-state spin structure of HD+
Charlotte M. König, Matthew Bohman, Fabian Heiße +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…

The electron mass from -factor measurements on hydrogen-like carbon C
Florian Köhler, Sven Sturm, Anke Kracke +3
The electron mass in atomic mass units has been determined with a relative uncertainty of , which represents a 13-fold improvement of the 2010 CODATA value. The…
