The elastic scattering of electrons from inert gases. III. Argon

Abstract

For pt.II see ibid., vol.14, p.307 (1981). The calculations of Fon et al. (1981) on electron-helium and electron-neon elastic scattering in which the atomic ground-state wavefunction is coupled with a 1P pseudo-state to include the full dipole polarisability, are extended to consider the elastic scattering of electrons from argon. Phaseshifts, differential, integral and momentum transfer cross sections for electrons elastically scattered from argon are reported for impact energies ranging from 3 to 150 eV. A critical assessment of previous theories and experimental measurements is made.
