论文摘要
我们报告了Rydberg Atoms和基态原子之间改变状态的碰撞的研究。我们采用高分辨率动量光谱来识别最终状态。与以前的研究相反，我们发现这种碰撞的结果不仅限于单个氢歧管。我们观察到在广泛的最终状态下人口的重新分布。我们还发现，即使是$ L $与初始状态相同的状态的衰减，但也可以使用不同的主量子数$ n $。我们在短暂的rydberg准分子络合物的框架中对基础物理过程进行了建模，其中电荷交换过程会产生振荡的电场，从而导致Rydberg歧管内的过渡。最终状态的分布显示出类似扩散的行为。
We report on the study of state-changing collisions between Rydberg atoms and ground state atoms. We employ high-resolution momentum spectroscopy to identify the final states. In contrast to previous studies, we find that the outcome of such collisions is not limited to a single hydrogenic manifold. We observe a redistribution of population over a wide range of final states. We also find that even the decay to states with the same $l$ as the initial state, but different principal quantum number $n$ is possible. We model the underlying physical process in the framework of a short-lived Rydberg quasi-molecular complex, where a charge exchange process gives rise to an oscillating electric field that causes transitions within the Rydberg manifold. The distribution of final states shows a diffusive-like behavior.
