摘要:

最近的理论研究与碱金属原子A $^{\ast}$激发到高里德堡态预测的存在超远程分子束缚态。这种激发的二聚体具有大的电偶极矩,与它们的长辐射寿命相结合,使它们成为应用中操纵的优秀候选者。这封信报告的Rb主系列线的自增宽的实验研究,揭示了多个卫星线翼。的卫星同意的位置定量与理论预测的最小值在激发远程里德堡态的Rb $_2$。

英文摘要:

Recent theoretical studies with alkali atoms A$^{\ast}$ 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 Rb$_2$.
