Abstract
The recent study by Joubert on effects of Coulomb repulsions in a many-electron system has focused attention on an integral identity involving the pair density. This has motivated the derivation presented here of a vectorial differential form related to this integral result. Our differential identity is then illustrated explicitly by using (i) an exact ground-state wave function for the so-called Hookean atom having external potential energy (1/2)kr(2), with k = 1/4, and (ii) Moshinsky's model in which both the interparticle interaction and the external potential are of harmonic type.
