    "abstract": "A simple way to generate low energy phase shifts for elastic scattering using\nbound-state calculations is postulated, validated and applied to the problem of\ne+ - Mg scattering. The essence of the method is to use the energy shift\nbetween a small reference calculation and the largest possible calculation of\nthe lowest energy pseudo-state to tune a semi-empirical optical potential. The\nL = 1 partial wave for e+ - Mg scattering is predicted to have a shape\nresonance at an energy of about 0.13 eV. The value of Zeff at the center of the\nresonance is about 1500.",
