镁原子自电离3pns态的能级位置和宽度

Energy Levels and Widths of Mg 3pns Autoionizing States

采用多通道量子数亏损理论与K矩阵相结合的方法,研究了镁原子3pns自电离态的光谱结构和特征.首次获得了包含精细结构的3p(?)ns自电离能级的位置和宽度.有关Mg3sns→3p(?)ns跃迁的光谱线形的计算结果与近期发表的实验结果相一致.

A combination of the multichannel quantum defect theory with the K-matrix is used to study spec-troscopic properties of Mg 3pns autoionizing states. The energy levels and widths with resolution of the 3pj fine-structures are reported for the first time. The present results of transition lineshapes are in good agreement with the recent experiment.
