Phase shifts, differential, total, and momentum-transfer cross sections are calculated using a pseudopotential approach for the elastic scattering of electrons by argon atoms in the impact energy range 0--20 eV. In the calculations, we use a pseudopotential for the electron-argon system based on a norm-conserving ionic pseudopotential derived by Bachelet et al. (Phys. Rev. B 26, 4199 (1982)) and screened by an exchange-correlation model potential suitably chosen for electron-scattering studies. The results are found to be in excellent agreement with existing experimental and theoretical data, proving the usefulness of this approach.
