Recent theoretical studies with alkali atoms A* excited to high Rydberg states predicted the existence of ultra-long-range molecular bound states. Such excited dimers have large electric dipole moments which, in combination with their long radiative lifetimes, make them excellent candidates for manipulation in applications. This Letter reports on experimental investigations of the self-broadening of Rb principal series lines, which revealed multiple satellites in the line wings. The positions of the satellites agree quantitatively with theoretically predicted minima in the excited long-range Rydberg states of Rb2.
最近对激发到高里德堡态的碱金属原子A*进行的理论研究预测了超长程分子束缚态的存在。这种激发的二聚体具有大的电偶极矩，再加上它们长的辐射寿命，使它们成为应用中操控的极佳候选者。本快报报道了对Rb主线系谱线自展宽的实验研究，该研究揭示了谱线翼区的多个卫星峰。这些卫星峰的位置与理论预测的Rb2激发长程里德堡态中的极小值定量相符。
