异质长程里德伯分子

Heteronuclear long-range Rydberg molecules

Michael Peper, Johannes Deiglmayr

摘要:

本文报道了在39K和133Cs的双粒子磁光阱中,通过单光子紫外光缔合作用,形成了同素的Cs2,K2和异素的CsK长程里德堡分子。不同的基态密度依赖的同质和异质光缔合速率和稳定的分子离子的自电离产生的检测提供了一个明确的分配。我们进行绑定绑定毫米波光谱的远程里德伯分子访问分子状态无法访问的单光子光缔合。基于最新的理论模型和原子参数的计算不能一致地再现来自同质和异质长程里德伯分子的全套数据。这表明,异质长程里德堡分子的光缔合和毫米波光谱为理论模型的发展提供了一个基准。

英文摘要:

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.
