我们首次在实验室直接测量了电子碰撞激发的高电荷类氢离子基态超精细分裂所产生的自发辐射。观察到类氢化合物{sup165}Ho{sup65+}的1{italS}{sup2}{italS}{sub1/2}组态的{italF}=4能级和{italF}=3能级之间的跃迁，并确定其波长为5726.4{正负}1.5。在考虑了相对论、核电荷分布、Bohr-Weisskopf和QED修正后，我们观察到这个原子核的核偶极磁矩与通常列表中的值有显著的偏差。{版权所有}{1996年美国物理学会。}
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.}
