中文摘要：
在磁光阱中利用双光子激发制各49S铯Rydberg原子，研究了超冷49S态原子在外加电场中的Stark效应和nS态原子与（n-4）多重态之间的避免交叉现象．利用态选择脉冲场电离方法测量并获得了避免交叉点附近的离子谱，测量了避免交叉点附近离子谱的变化情况，并观察到避免交叉点附近由相互作用导致的态转移现象．
英文摘要：
The Stark effect of ultra-cold Cs Rydberg atom is investigated in a magneto-optical trap, and the avoided crossing between nS state and （n - 4） manifold is observed. The ion spectrum near the avoided crossing is obtained by using state-selective field pulse ionization technique. By changing the intensity of the applied electric field, we find that the relative intensities of two Stark states near the avoided crossing exchange obviously. Furthermore, state transfer from nS Rydberg state to high-l state due to the avoided crossing is also obtained.
