摘要
本文采用Sampson等的“Z标度类氢模型和库仑-玻恩交换近似”方法,修改了Sampson理论中关于屏蔽常数的定义,在计算屏蔽常数时,选用电子轨道的平均半径标准,使用多组态狄拉克福克程序包(MCDF)计入了高荷电靶离子的相对论效应,计算了类Ne离子激发能级通过类Na离子内层电子碰撞电离布居的反应速率系数。
Abstract
In order to further clarify the soft-X-ray laser kinetics of Ne-like ions, the rate coefficients for populating excited levels of Ne-like ions by electron-impact ionization of lnner-subshell electrons of Na-like ions have been calculated by using Coulomb-Born exchange method and the Z-scaled hydrogenio model, in which the screening constant was defined and evaluated with the Multi-Configurational Dirac-Fock'(MCDF) mean radius of the initial orbital of the active electron to consider the combined-effects of relativity and screening in an actual transition calculation.
