Measurement of lifetime of ultracold cesium Rydberg states

摘要: 本文从实验上采用两步激发超冷基态原子获得超冷Rydberg原子，通过选择场电离的方法获得超冷Rydbetg原子的离子信号．改变延迟时间测得Rydberg原子布居数随时间的变化关系，用两种方法拟合实验数据得到36D和34S态原子的有效寿命，与现有理论结果一致．
- Rydberg原子 /
- 寿命 /
- 黑体辐射 /
- 场电离
Abstract: In this paper, the cold cesium atoms are excited to Rydberg states via two-photon transition and the ion signal of Rydberg atoms is obtained by the selective field-ionization method. The evolution of the 36D and 34S states population is acquired by changing delay time; the corresponding effective lifetimes are obtained by fitting the experimental data, which are in agreement with the existing theoretical results.
