title: Note: The weak-correlation limit of the three-electron harmonium atom.
abstract: Asymptotic energy expressions for the weak-correlation limits of the two lowest energy states of the three-electron harmonium atom are obtained in closed forms. When combined with the known results for the strong-correlation limit, these expressions, which are correct through the second order of perturbation theory, yield robust Padé approximants that allow accurate estimation of energies in question for all magnitudes of the confinement strength.
