Abstract

The electron-impact ionization cross sections for all neutral ground-state elements H-Xe (Z = 1 to Z = 54) have been calculated using the plane wave Born approximation. The atomic orbital wavefunctions have been approximated by Roothaan-Hartree-Fock Slater functions, and the scattered and ejected electrons have been approximated by a plane wave and Coulomb wave, respectively. Full orthogonalization of the Coulomb wave with the occupied atomic orbitals has been performed, which improves the correspondence with experimental data at low- and mid-energies. Results are presented for the total ionization cross section and the partial ionization cross sections of the largest contributing orbitals for each atom.
