The differential cross section and the asymmetry function of the elastic scattering of electrons from screened nuclei were computed at 10-deg intervals from 10° to 170°. We report here the results of the calculation for (1) gold, with electron energies of 400, 200, 188, 120, 100, and 50 keV; (2) copper, with electron energies of 400, 200, 100, and 50 keV; and (3) mercury, with electron energy of 204 keV. The screening potentials used were a three-terms exponential potential for gold, a two-terms exponential potential for copper, and the Hartree potential for mercury. The modified method of the summation of the phase shifts series leads to improved accuracy. The error in the calculated cross section and the asymmetry function is estimated to be not greater than one percent. All results together with the corresponding calculations for Coulomb field are given in tabulated form.
