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.
