论文摘要
我们研究了高轨道量子数的超冷rydberg原子的孤立核心激发。在$ 6S_ {1/2} 40L \ rightarrow 6p_ {1/2} 40L $ transition上进行测量,$ l = 5-9 $。提取的能量转移和自动化速率与基于独立电子的模型非常吻合,同时考虑了扰动方法的相互作用。我们揭示了与轨道量子数的自动化速率特别长的持久性,与先前研究的分区原子相比,$ 6p_ {1/2} nl $自动取代状态与$ 5D_ {3/2}εl'$ continua的强烈耦合。
We study isolated core excitation of ultra cold ytterbium Rydberg atoms of high orbital quantum number. Measurements were performed on the $6s_{1/2} 40l \rightarrow 6p_{1/2} 40l $ transition with $l=5-9$. The extracted energy shifts and autoionization rates are in good agreement with a model based on independant electrons, taking into account interactions in a perturbative approach. We reveal a particularly long persistence of the autoionization rates with the orbital quantum number, explained by the strong coupling of the $6p_{1/2}nl$ autoionizing state with the $5d_{3/2}εl'$ continua compared to previously studied divalent atoms.
