最近，依赖时间的紧密耦合方法已被应用于计算 Kr、W 和 Pb 原子的电子碰撞直接电离截面。对这三个重中性原子系统进行了概述。当直接电离截面与激发自动电离截面相结合时，发现总电离截面与 Kr 和 Pb 的交叉束测量结果相当一致。
The time-dependent close-coupling method has been recently applied to calculate electron-impact direct ionization cross sections for the Kr, W, and Pb atoms. An overview is presented for these three heavy neutral atom systems. When the direct ionization cross sections are combined with excitation-autoionization cross sections, the total ionization cross sections were found to be in reasonable agreement with crossed-beams measurements for Kr and Pb.
