摘要

通过超冷铯原子光缔合制备激发态的超冷铯分子. 利用冷原子荧光频率调制技术获得了超冷铯分子第一激发态6S1/2+6P3/2离解限0g-长程态高分辨振转光谱, 计算得到0g- 长程态振动量子数从0到51的不同振动能级的转动常数, 和Daniel研究小组的理论结果符合得很好.

In this paper, high-resolution vib-rotational spectrum of ultracold cesium molecule in its first excited state of 6S1/2+6P3/2 with dissociation limit 0g- long range state is obtained by cold atom fluorescence frequency modulation method. The rotation constants of different vibration energy levels of cesium molecule for vibrational quantum number from 0 to 51 are achieved. The results are in good agreement with the theoretical results given by Daniel.
