摘要
本文在Z标度类氢模型算法下,采用库仑-玻恩交换近似和改善的屏蔽常数定义,计算了类钠铜离子和类钠水窗两端的硒和锝离子的内外壳层电子的电子碰撞直接电离和非直接激发自电离的速率系数和截面.
The electron-impact ionization results for Na-like Cu, Se and Tc ions including inner-shell electrons ionization and excitation-autoionization were obtained by using Coulomb-Born-exchange approximation and Z-scaled hydrogenic model in which the definition and evaluation of the screening constant were improved.
