we demonstrated a high sensitive trap-loss spectroscopy technique by modulating fluorescence of cold atoms in magneto-optical trap, which allow a direct spectroscopy detection of the rovibrational levels with a very weak transition probability. The low-lying vibrational spectroscopy of upsilon = 3 approximately 17 of Cs(2) 0g- pure long-range state have been observed with rotational structures, which are well resolved up to J = 8. The rotational constants are obtained by fitting experimental data to a nonrigid rotation model.
我们通过调制磁光阱中冷原子的荧光，展示了一种高灵敏度的陷阱损失光谱技术，该技术能够对具有非常弱跃迁概率的振转能级进行直接光谱检测。已观测到Cs(2) 0g - 纯长程态中υ = 3至约17的低振动光谱，其具有转动结构，在J = 8之前都能很好地分辨。通过将实验数据拟合到非刚性转动模型来获得转动常数。
