Calculation of atomic energy using partial-wave method for plasmas at medium-low temperature

On the basis of the improved averaged atomic model, the distribution of the free electrons is dealt with by the partial-wave method to improve the precision of determination of the energy level, electron populations and atomic inner energy. The obtained results of atomic energy for ground state are in rather good agreement with that of Hartree-Fock method. As samples, the total electron energies of W, Au, Rn and Am are calculated respectively.
