| 摘 要： | 报道了对铯原子在双光子激发条件下的强电场光电离光谱进行实验研究的结果。发现钩原子较大量子亏损导致的核心效应可影响到场电离阈值以上的光谱特性，但对零场阈值附近强场共振特性的影响可以忽略。

| Abstract: | The two-photon ionization spectrum of Cs atom in a strong electric field wasstudied experimentally.It was found that the core effect of Cs atom due to the higherquantum defects can affect the ionization spectrum well above the field ionization threshold,but has negligible influence on the strong field resonances near the zero field ionizationthreshold.The dependance of the strong field resonance on the polarization of the excitationlaser beam seems not fully consistent with predictions and a further study is needed. |
