我们观察到强线偏振超短激光脉冲导致氩二聚体多重受挫隧道电离诱导解离。通过测量多达八倍电离氩二聚体的库仑爆炸的动能释放和角分布，我们可以追踪在激光脉冲结束时将最多两个电子重新捕获到高电荷化合物的里德堡态。在二聚体解离后，里德伯电子更倾向于定位在具有较高电荷态的原子离子处。我们通过延时弱脉冲探测电子重捕获动力学。
We observe multiply frustrated tunneling ionization-induced dissociation of the argon dimers by intense linearly polarized ultrashort laser pulses. By measuring the kinetic energy release and angular distribution of the Coulomb explosion of up to eightfold ionized argon dimers, we can trace the recapture of up to two electrons to Rydberg states of the highly charged compound at the end of the laser pulse. Upon dissociation of the dimer, the Rydberg electron prefers to localize at the atomic ion with the higher charge state. We probe the electron recapture dynamics by a time-delayed weak pulse.
