This is the authors' abstract. We don't add key points for this paper.
The α-parametrized Hartree-Fock-Slater (Xα) equations are solved in the framework of Z^-1 expansion theory for the two- and four-electron ions in their ground-state configurations (1s²) and (1s²2s²), respectively. The first two terms in the Z^-1 expansion of α are given when α is determined by various criteria.
