The authors report an observation of the spontaneous M1 transition due to the hyperfine splitting of the ground state of a highly charged hydrogen-like ion in an ion trap. The transition between the F=4 and F=3 levels of the 1s {sup 2}S{sub 1/2} configuration of hydrogen-like {sup 165}Ho{sup 66+} was observed and its wavelength was determined to (5726.4{plus_minus}1.5) {Angstrom}. The authors observe a significant deviation (89 {Angstrom}) from a recent prediction. After having taken into account relativistic, nuclear charge distribution, Bohr-Weisskopf and estimated QED corrections, they use the measured splitting to determine the dipole magnetic moment of the {sup 165}Ho nucleus. The value obtained differs from the tabulated value used in the prediction and confirms the results of a recent measurement. With this new value, their measurement confirms the magnitude of the different terms contributing to the splitting, used in the prediction of this hyperfine transition. This measurement with H-like highly charged ions complements techniques using muonic and other exotic hydrogenic atoms. However, experimental data are only available for {sup 209}Bi{sup 82+}. This method can be applied to many H-like ions with splittings in the VIS or UV range.
