摘要

利用双光子激发超冷原子获得70S超冷Cs Rydberg原子, 采用脉冲场电离法使Rydberg原子电离, 并用微通道板测量Rydberg原子的信号. 改变激发光和电离电场脉冲的延迟时间和激发光脉冲的宽度, 研究70S超冷Cs Rydberg原子之间的相互作用和动力学演化过程. 利用黑体辐射导致的态转移和相互作用碰撞电离解释了实验结果,实验结果和理论相一致.

Ultracold 70S Cs Rydberg atoms are obtained by two-photon excitation in a magneto-optical trap, and detected by using the state-selective pulse field ionization technique. The evolution of 70S Rydberg atoms is investigated by changing the delay time between excitation laser and ionization electric field and the excitation duration. Blackbody radiation is taken into account to explain experimental result. The experimental result is found to be consistent with theoretical value.
