Calculations of the exchange asymmetry in elastic scattering of electrons by sodium atoms are reported at incident electron energies of 10 and 54.4 eV. The close-coupling calculations are performed with the four lowest target states of the sodium atom. At 10 eV, the present calculations predict nearly pure singlet-state scattering and nearly pure triplet-state scattering at certain angles. At 54.4 eV, the theoretical results are compared with recent measurements. Qualitative agreement is obtained, although some discrepancy remains.
