在实验和理论相结合的努力中，我们报告了两种新型超冷长程里德伯分子。首先，我们演示了在单步光缔合中创建一个里德伯原子和两个基态原子的三原子分子。其次，我们分配了一系列激发二聚体状态，这些状态受到迄今为止尚未探索的机制的束缚，该机制基于陡峭电位下降的内部量子反射。这项工作中确定的里德伯分子的特性使它们成为超冷温度下新型化学的原型。
In a combined experimental and theoretical effort we report on two novel types of ultracold long-range Rydberg molecules. First, we demonstrate the creation of triatomic molecules of one Rydberg atom and two ground-state atoms in a single-step photoassociation. Second, we assign a series of excited dimer states that are bound by a so far unexplored mechanism based on internal quantum reflection at a steep potential drop. The properties of the Rydberg molecules identified in this work qualify them as prototypes for a new type of chemistry at ultracold temperatures.
