Abstract

We develop the double - parameter perturbation method to study the ground state energies of lithium-like atoms. The calculated first-level approximate results are in well agreement with experiment within a relative error of 0.2%.

Key words： double-parameter perturbation method; lithium-like atom; ground state energy
