论文摘要
我们报告了$ {}^{173} $ yb和$^{133} $ cs之间的磁性feshbach共振的第一个观察结果。在$（f = 3，m_f = 3）中制备的CS原子的混合物中，$状态和未铝的费米子$ {}^{173} $ yb，我们观察到由于两组磁性feshbach共振而产生的共振原子损失，左右是622〜G和702〜g。单个YB核自旋组件的共振$ M_ {i，\ mathrm {yb}} $通过与CS电子自旋的相互作用而分开，这也为观察到的谐振提供了主要的耦合机制。观察到的分裂和相对共振强度与耦合通道计算的理论预测非常吻合。
We report the first observation of magnetic Feshbach resonances between ${}^{173}$Yb and $^{133}$Cs. In a mixture of Cs atoms prepared in the $(f=3, m_f=3)$ state and unpolarized fermionic ${}^{173}$Yb we observe resonant atom loss due to two sets of magnetic Feshbach resonances around 622~G and 702~G. Resonances for individual Yb nuclear spin components $m_{i,\mathrm{Yb}}$ are split by its interaction with the Cs electronic spin, which also provides the main coupling mechanism for the observed resonances. The observed splittings and relative resonance strengths are in good agreement with theoretical predictions from coupled-channel calculations.
