A new point-ion pseudizing potential for s-p bonded metals

The authors have developed a new point-ion pseudizing potential appropriate for the s-p bonded metals. The electron-ion contribution to the effective potential has been calculated self-consistently. The essential feature of this description is the occurrence of the true field rather than a coulombic form in the pre-asymptotic region. The orthogonalizing contributions that arise from repulsive s scattering and attractive p scattering are calculated in terms of delta functions of strengths suitable for achieving the necessary s and p pseudizations respectively. The new potential is successfully applied to calculate a number of solid and liquid state properties of certain s-p bonded systems.
