Abstract
A new method for solving the central equation of the optimizedeffective potential method is presented and applied to theexchange-only, orbital-dependent energy functional. Theoptimized local potential is written as the sum of a Slaterexchange potential, that gives the exact asymptotic behaviour,plus a short-range correction represented by a linearcombination of L2-functions. The method is easy to implement, can also be efficiently applied to molecules and clusters and gives high-quality results. Energies, eigenvalues and densities obtained for closed-shell atoms are compared withthe corresponding Hartree-Fock quantities.
