Elastic scattering of electrons and positrons by the cadmium atom is studied. A real optical potential is used to calculate the phase shifts of the first few partial waves. Then the differential cross sections (DCS's) are calculated from the formula given by Nesbet (Phys. Rev. A 20, 58 (1979)) using the calculated phase shifts of the first few partial waves. The calculations are performed at incident projectile energies of 40, 60, 75, 85, 100, and 150 eV, where the experimental DCS measurements for electron scattering are available. The agreement between our calculated DCS and the available experimental DCS is reasonable at lower energies and very good at higher energies. Total cross sections are also obtained, but no other results, theoretical or experimental, are available for comparison with them.
