Abstract

In this work, we have studied the ground state energy of atomic systems using electron gas approximation. We evaluate the correlation energy for neutral atoms using a semiclassical method induding the Dirac's exchange-term in the energy functional. The results obtained show good agreement compared with exact values specially for Z = 2 to 18.
