    "abstract": "Positron binding to anions is investigated within the work formalism proposed\nby Harbola and Sahni for the halide anions and the systems Li^- through O^-\nexcluding Be^- and N^-. The toal ground-state energies of the anion-positron\nbound systems are empirically found to be an upper bound to the Hartree-Fock\nenergies. The computed expectation values as well as positron and positronium\naffinities are in good agreement with their restricted Hartree-Fock\ncounterparts. Binding of a positron to neutral species is also investigated\nusing an iterative method.",
