Abstract
For a specific force constant, the spatial form of the ground-state wavefunction Psi(r(1),r(2)) is known analytically for the Hookean atom in which two electrons repel coulombically. Hen, it is first shown that the wavefunction Psi(r,r) for the antiparallel spin electrons at the same position r is sufficient to construct the ground-state density in this model example. An off-diagonal generalization is then effected, which relates the one-particle density matrix to the electron pair correlation function, again for this same model. (C) 2000 Elsevier Science B.V.
