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.
