论文摘要
我们介绍了通过单核光光TRAP的39K和133Cs的单核紫外光照射聚合物，在双物种磁光陷阱中形成了同核CS2，K2和异核CSK远程Rydberg分子。同核和异核光相关率的不同地面密度依赖性以及自动离子化引起的稳定分子离子的检测提供了明确的分配。我们对远程Rydberg分子进行界限界限毫米波光谱，以访问一光照射的分子状态。基于最新的理论模型和原子参数的计算不会始终从同型和异核长期rydberg分子中重现完整的数据。这表明异核远程Rydberg分子的光缔合和毫米波光谱为理论模型的发展提供了基准。
We present the formation of homonuclear Cs2, K2, and heteronuclear CsK long-range Rydberg molecules in a dual-species magneto-optical trap for 39K and 133Cs by one-photon UV photoassociation. The different ground-state-density dependence of homo- and heteronuclear photoassociation rates and the detection of stable molecular ions resulting from auto-ionization provide an unambiguous assignment. We perform bound-bound millimeter-wave spectroscopy of long-range Rydberg molecules to access molecular states not accessible by one-photon photoassociation. Calculations based on the most recent theoretical model and atomic parameters do not reproduce the full set of data from homo- and heteronuclear long-range Rydberg molecules consistently. This shows that photoassociation and millimeter-wave spectroscopy of heteronuclear long-range Rydberg molecules provide a benchmark for the development of theoretical models.
