我们对171 Yb+离子的基态进行了微波-光学双共振实验。约105个粒子被限制在一个r.f.在He缓冲气体的存在下，四极阱持续几个小时的时间。超精细泵浦的脉冲染料激光器，其次是微波跃迁，我们观察到通过离子荧光强度的变化。基态超精细分裂为DW =12642812124.2± 1.4Hz。在该实验中获得的最终线宽为33 mHz，对应于3.8·1011的线Q。gD W的最终误差主要取决于可用频率基准的精度。
We performed a microwave-optical double resonance experiment on the ground state of171Yb+ ions. About 105 particles were confined in a r.f. quadrupole trap for periods of several hours in the presence of He buffer gas. Hyperfine pumping by a pulsed dye laser was followed by microwave transitions, which we observed via changes in the ionic fluorescence intensity. The ground state hyperfine splitting has been determined togD W=12642812124.2±1.4 Hz. The ultimate line width obtained in this experiment was 33 mHz, corresponding to a lineQ of 3.8·1011. The final error ofgD W is mainly determined by the accuracy of the available frequency reference.
