钡原子6_(p3/2ns)自电离里德伯态的研究

Study of the Ba 6_(p3/2ns) Autoionizing Rydberg States

用激光多步激发技术研究了处于 6 p 电离限以下的 6 p ns自电离态的光谱。并利用最新的 R矩阵的计算结果 ,结合多通道量子亏损理论进行了理论分析。理论结果与实验光谱相符合。

Using a multi step laser excitation technique, the excitation spectra of the Ba 6p 3/2 ns (J=1) autoionizing states below the 6p 1/2  limit are studied. The experimental data are compared with the results of an R matrix  calculation combined with multichannel quantum defect theory (MQDT). The agreement between experiment and theory is satisfactory.
