A coupled-channel optical method for electron-atom scattering is applied to elastic electron-sodium scattering at energies of 20, 22.1, 54.4, 100, and 150 eV. It is demonstrated that the effect of all of the inelastic channels on elastic scattering may be well reproduced by the {ital ab} {ital initio} calculated complex nonlocal polarization potential. The results are found to be in good agreement with the recent experiments of Lorentz and Miller (unpublished).
