Abstract
In an earlier work by Holas et al. [ A. Holas, I. A. Howard, N. H. March. Phys. Lett. A, 310, 451 ( 2003)], the ground-state electron density rho(r) for model two-electron spin-compensated atoms was obtained in terms of the relative motion wave function for the case of harmonic confinement and arbitrary interparticle interaction u(r(12)). Following recent interest in the s-wave approximation to rho(r) for Coulombic potential energy e(2)/r(12) at separation r(12) between the electrons, we here consider both harmonic interaction u(r(12)) proportional to r(12)(2) and also the inverse square law 1/r(12)(2). The interplay between correlation and confinement clearly emerges in such spin-compensated models of interacting inhomogeneous electron liquids.
