论文摘要
我们考虑了$^{176} $ lu $^+$中时钟过渡的超精细介导的效果。由于超精细相互作用而导致的良好结构水平的混合会给给定状态带来对Landé$ g $ factors和四极力矩的修改。 $ g $因子和四极矫正都得出了明确的表达式，为此，核磁偶极子耦合产生了领先的顺序项。进行了$ g $ factor的高精度测量值，用于$^1S_0 $和$^3D_1 $超精细水平，这提供了对领先订单校正条款的实验确定。
We consider hyperfine-mediated effects for clock transitions in $^{176}$Lu$^+$. Mixing of fine structure levels due to the hyperfine interaction bring about modifications to Landé $g$-factors and the quadrupole moment for a given state. Explicit expressions are derived for both $g$-factor and quadrupole corrections, for which leading order terms arise from the nuclear magnetic dipole coupling. High accuracy measurements of the $g$-factors for the $^1S_0$ and $^3D_1$ hyperfine levels are carried out, which provide an experimental determination of the leading order correction terms.
