Title
The central role of the von Weizsacker kinetic energy density in determining the energy functional of a model two-electron atom with harmonic confinement and inverse square interparticle repulsion
Author
Abstract
This study uses an analytically known expression for the relative motion wave function for the Crandall et al. two-electron model atom with harmonic confinement plus inverse square law interparticle repulsion. This wavefunction is then employed to calculate the kinetic energy density for chosen values of both the harmonic force constant and the strength of the interaction coupling. Further consideration is then given to the Gal-March energy density functional which is shown to depend on the von Weizsacker kinetic energy density in a fundamental manner.
