【摘要】 介绍了一种可调谐激光三步孤立实激发方式测量外电场中原子自电离态光谱的技术。利用该技术结合适当的激光偏振组合方式 ,系统地测量了大量的 Ba原子初态为 M=0和 |M|=1 Stark态的 6pnk自电离态光谱 ,并且对这些实验光谱进行了初步的分析。分析结果得出这些自电离态光谱由于电场的作用 ,它们之间产生了强烈的混和从而导致了它们线形的变化。更多还原

【Abstract】 We present a isolated core excitation method for producing the autoionizing states in the electric fields. Many experimental autoionizing states excited from both M =0 and | M |=1 Stark initial states were measured with this method combined with a proper polarization configuration. Furthermore, the preliminary discussions conclude that the profile of autoionizing states in the electric field becomes more complex due to the mixing of the electric fields.更多还原
