    "abstract": "The Configuration Interaction (CI) method is applied to the calculation of\nthe structures of a number of positron binding systems, including e+Be, e+Mg,\ne+Ca and e+Sr. These calculations were carried out in orbital spaces containing\nabout 200 electron and 200 positron orbitals up to l = 12. Despite the very\nlarge dimensions, the binding energy and annihilation rate converge slowly with\nl, and the final values do contain an appreciable correction obtained by\nextrapolating the calculation to the l to infinity limit. The binding energies\nwere 0.00317 hartree for e+Be, 0.0170 hartree for e+Mg, 0.0189 hartree for\ne+Ca, and 0.0131 hartree for e+Sr.",
