Abstract:
A scheme for correlation energy corrections Ec based on asymptotic properties of the effective pair distribution function g(r1; r2) and correlation energy densities ϵc{ϱ(r1)} has been considered. To obtain ϵc{ϱ(r1)} model functions g(r1; r2) are used in the local spin density approximation (LSDA). This model yields the correct high-density limit for the homogeneous electron gas ϵc{ϱ} and reproduces empirical Ec values with an average error amounting to 2.2% for the first- and second-row closed-shell atoms, 5.6% for the first-row hydrides XH and 3.4% for the second-row hydrides XH.
