Effective potentials for electron-atom scattering below inelastic thresholds. II. The finite-range problem

For pt.I see ibid., vol.10, p.2639 (1977). Elastic scattering of electrons by atoms is considered in the approximation of using polarised atom states, which gives a system of coupled differential equations. Solutions for large r(r>r N ) are obtained using the method of the previous paper in this series. Solutions in the finite range 0
