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 $g$ factor, $g_{e,\mathrm{bound}} = -2.002\,278\,54…
