摘要
本文在库仑-玻恩交换近似下,用改善了的Sampson的Z标度类氢模型及Grant等的多组态Dirac-Fock(MCDF)程序包,计及了高荷电靶离子的相对论效应,计算了元素Zn的类Na离子L层电子碰撞电离产生的类Ne Zn离子n=3激发能级布居的速率系数.得出的该值比采用原始的Sampson等方法的计算结果降低了25%左右.
Rate coeffients for populating n=3 excited levels of Zincic Ne-like by eletron imact ionization of L-shell of Na-like Zinc have been calculated by using improved Sampson's Z-scaled hydrogenic model and Grant's Multi-Configurational Dirac-Fock(MCDF) program package and including relativistic effect of high charged targed ions under Coulomb-Born exchang approximation. The present results are vompared with those obtained using the Sampson's approach and found to be lower by 25% or so.
