Differential and transport electron-atom elastic scattering cross sections have been computed for a number of selected atomic targets in the electron energy range 500-4000 eV. The phase shifts have been computed by numerically solving the Dirac equation for a central electrostatic field up to a large radius where the atomic potential becomes negligible. The atomic potential was that of Hartree-Fock for the atomic numbers <=18 and that of Hartree-Fock-Dirac-Slater for the atomic numbers > 18. Good accordance with previous theoretical computations and experimental data has been found.

Abstract
Differential and transport electron-atom elastic scattering cross sections have been computed for a number of selected atomic targets in the electron energy range 500-4000 eV. The phase shifts have been computed by numerically solving the Dirac equation for a central electrostatic field up to a large radius where the atomic potential becomes negligible. The atomic potential was that of Hartree-Fock for the atomic numbers <=18 and that of Hartree-Fock-Dirac-Slater for the atomic numbers > 18. Good accordance with previous theoretical computations and experimental data has been found.File in questo prodotto:
