| dc.description | We have derived non-Coulomb phase shifts from measured differential cross sections for electron scattering by the ions Na<sup>+</sup>, Cs<sup>+</sup>, N<sup>3+</sup>, Ar<sup>8+</sup> and Xe<sup>6+</sup> at energies below the inelastic threshold. Values of the scaled squared deviation between the observed and fitted differential cross sections, χ<sup>2</sup>, for the best-fit phase shifts were typically in the range 3-6 per degree of freedom. Generally good agreement with experiment is obtained, except for wide-angle scattering by Ar<sup>8+</sup> and Xe<sup>6+</sup>. Current measurements do not define phase shifts to better than ≈ 0.1 rad even in the most favourable circumstances and uncertainties can be much larger. |
