Elastic scattering of electrons from Helium-like positive ions

The adiabatic exchange method is used to calculate the elastic scattering phase shifts for electrons scattered from the positive ions Li⁺ to Ne⁸⁺ of the helium isoelectronic sequence for energies from 0 to 144 rydberg. Exchange is treated exactly and accurate dipole polarization potentials are included. Comparisons with previous work are given where possible.
