The photoionization of excited hydrogen atom in plasmas. (English) Zbl 1219.82160
Summary: The photoionization processes of excited hydrogen atoms in plasma environments are investigated using the method of complex coordinate rotation. The standard Debye-Hückel model and modified Debye-Hückel model are adopted to describe the plasma screening effects. The photoionization cross sections of plasma-embedded excited hydrogen atoms varied with different screening lengths are displayed to illustrate the influence of plasma screening. The results of the Debye-Hückel model compared with the modified Debye-Hückel are presented. The shape resonances and Cooper minima due to the plasma screening are observed and discussed.
