本文报道了用斯塔克干涉技术测量镱原子中高度禁戒的$6s^2^1S_01到5d6s^3D_1 $磁偶极跃迁。这个振幅在解释未来利用相同跃迁的宇称不守恒实验中是很重要的。我们找到$||~ = ~ 1.33（6）_{Stat}（20）_{\beta} \times 10^{-4} \mu_0$，其中较大的不确定性来自先前测量的矢量跃迁极化率$\beta$。M1的振幅很小，不应该限制宇称不守恒实验的精度。
We report on a measurement of the highly forbidden $6s^2 ^1S_0 \to 5d6s ^3 D_1$ magnetic-dipole transition in atomic ytterbium using the Stark-interference technique. This amplitude is important in interpreting a future parity nonconservation experiment that exploits the same transition. We find $| | ~ = ~ 1.33(6)_{Stat}(20)_{\beta} \times 10^{-4} \mu_0$, where the larger uncertainty comes from the previously measured vector transition polarizability $\beta$. The $M1$ amplitude is small and should not limit the precision of the parity nonconservation experiment.
