    Ionization state distribution is one of the widely used physical quantities in plasma physics, whereas atomic data are the precondition for the evaluations. Firstly, Rubiano's relativistic atomic model, Faussurier's non-relativistic atomic model and More's highly simplified atomic model are utilized to calculate energies of multiply-ionized species for Fe element. The comparisons with the results by corrected Hartree-Fock calculations show that the data obtained by Faussurier's atomic model are the most reliable and accurate among them. Secondly, the variations of average ionization states and ion abundances for LTE Fe-plasmas with temperature and density are studied based on the atomic data from above models. Numerical values show that these data from different models exert a little influence upon average ionization states, but can affect remarkably the ion abundance in plasmas. Finally, the mechanism for this kind of distinction is physically elucidated.作者简介:郭永辉.E-mail: gyh661012@163.com.通讯作者
