We report the first direct laboratory measurement of the spontaneous emission due to the hyperfine splitting of the ground state of a highly charged hydrogenlike ion excited by electron collisions. The transition between the {ital F}=4 and {ital F}=3 levels of the 1{ital s}{sup 2}{ital S}{sub 1/2} configuration of hydrogenlike {sup 165}Ho{sup 65+} was observed and its wavelength was determined to 5726.4{plus_minus}1.5. After taking into account relativistic, nuclear charge distribution, Bohr-Weisskopf, and QED corrections, we observe a significant deviation from commonly tabulated values of the nuclear dipole magnetic moment of this nucleus. {copyright} {ital 1996 The American Physical Society.}
