A coupled-channel optical method for electron-atom scattering is applied to electron-sodium scattering at energies of 10, 20, 22.1, 40, 54.4, and 100 eV. The 3 {sup 2}{ital S}, 3 {sup 2}{ital P}, and 3 {sup 2}{ital D} channels are coupled explictly whereas the rest of the one-electron excited states of the atom are taken into account via the {ital ab} {ital initio} complex nonlocal polarization potential. The 3 {sup 2}{ital S}--3 {sup 2}{ital S} and 3 {sup 2}{ital S}--3 {sup 2}{ital P} differential cross sections are found to be in good agreement with recent experiments of Lorentz and Miller (unpublished). The effect of the polarization potential does not change the qualitative results of a standard coupled-channel calculation, but improves agreement with the experiment. Integrated and total cross sections are also presented.
