论文摘要
在较少电子原子系统的三个主要类别中，非偏见的光电效应的差异和总横截面得出了封闭的分析公式：（1）中性原子和带电的原子离子，这些原子和带正负的原子离子含有多个绑定的电子，（2）负电荷的原子离子和（3）一个元素，（3）eNOMEN-ELECEMS和ELECTRON和ELECTRON和ELCECTRON和ICEMS和ICEMS和ICENS和ICENS和ICENS and and和Ict and and and和Isc。我们在这项研究中开发的程序是QED方法的组合以及原子和离子获得的密度功能理论的结果。在所有这些系统中，光电效应被视为最外部电子的光电检查，我们的分析基于这些原子系统中电子密度（radial）分布获得的密度功能理论的结果。在较早的研究中，从未产生（1）和（2）的原子系统的光电效应的差异和总横截面的分析公式（类似于我们的）。
Closed analytical formulas are derived for the differential and total cross sections of the non-relativistic photoelectric effect in the three main classes of few-electron atomic systems: (1) neutral atoms and positively charged atomic ions which contain more than one bound electron, (2) negatively charged atomic ions, and (3) one-electron atoms and ions. Our procedure developed in this study is a combination of QED methods and results of the density functional theory obtained for atoms and ions. In all these systems the photoelectric effect is considered as photodetachment of the outer-most electron and our analysis is based on the results of density functional theory obtained for the electron density (radial) distribution in these atomic systems. Analytical formulas (similar to ours) for the differential and total cross sections of photoelectric effect for atomic systems from classes (1) and (2) have never been produced in earlier studies.
