论文摘要
$^3 $ p $^{\ circ} _2 $状态的hyperfine常数已使用三种不同的偶极转换测量。最近显示，该状态具有相对较大的超细磁八极分裂，因此具有令人困惑的磁性八极矩。测量是在快速原子束上使用共线激光光谱进行的，该光谱为探测具有高分辨率的长寿命亚固定原子态提供了直接的途径。从对这三行的组合分析中，我们没有发现$^{173} $ yb中非零的八杆力矩的显着证据。
The hyperfine constants of the $^3$P$^{\circ}_2$ state in neutral Yb have been measured using three different dipole transitions. This state was recently shown to have a comparatively large hyperfine magnetic octupole splitting, and thus a puzzlingly large magnetic octupole moment. The measurement is performed using collinear laser spectroscopy on a fast atomic beam, which provides a straightforward route to probing long-lived metastable atomic states with high resolution. From the combined analysis of all three lines we find no significant evidence for a non-zero octupole moment in $^{173}$Yb.
