Abstract
Using classical electrostatics the total effective integrated chargedensity function is calculated for Be and Ne using the multiplicative potentials derived from 1 Hartree and 2 Hartree–Fock approximation to quantal density functional theory 3exchangeonly optimized effective potential and 4 Kohn–Sham exchangecorrelation potential using the quantum Monte Carlo density The evolution of effective integrated chargedensity function for these atoms is examined as the electron correlation is built up stepwise from its absence to the stage of its near complete presence These results provide a deeper understanding of the Kohn–Sham exchangecorrelation potential in terms the correspondingly defined integrated chargedensity functions based on the Poisson equation
