Title
Exact Hamiltonian for an analytic correlated ground-state wave function for He-like ions
Author
Abstract
A correlated three-parameter variational ground-state Psi(r(1), r(2), r(12)) proposed by Chandrasekhar for helium-like ions gives a high percentage of the electron correlation energy resulting from the interaction energy e(2)/r(12) and also yields an analytic ground-state electron density rho(r). Here, we extract via Schrodinger equation an exact Hamiltonian for which the Chandrasekhar wave function is the ground-state. Properties of the potential energy function in this Hamiltonian are quantified. Finally, kinetic energy densities are plotted and related to the Laplacian of rho(r). (C) 2008 Elsevier B.V.
