三步孤立实激发技术在原子自电离态光谱测量中的应用

Application of Three-step Isolated-core Excitation Technique on Measuring Atomic Autoionizing Spectra

三步孤立实激发技术是一种有效的测量原子自电离态光谱的方法.将该技术结合激光偏振组合应用于碱土金属Ba原子的光谱测量,获得了具有不同总角动量的Ba原子自电离态光谱,其中大部分为首次获得的数据.测量结果和理论计算结果进行比较,结果相当令人满意.

Three-step isolated-core excitation is an effective method of measuring atomic autoionizing spectra. Using this method together with the polarization combination of lasers, we obtained many data of Ba autoionzizing states, most of which was obtained at the first time. Finally, the measurements were compared to the theoretical calculations. The result is satisfied.
