The elastic scattering of electrons from inert gases. II. Neon

Abstract

For pt.I see ibid., vol.14, p.307 (1981). The R-matrix calculations of Fon et al (1981) on electron-helium elastic scattering are extended to consider the elastic scattering of electrons from neon in which the Ne ground-state wavefunction is coupled with a ¹P pseudo-state to include the full state dipole polarisability. Phaseshifts, differential, integral and momentum transfer cross sections for electrons elastically scattered from neon are reported for the impact energy range of 4 to 200 eV. A search has also been carried out for the 'critical energy' and 'critical angle' where maximum spin polarisation of the incident electrons may be expected after scattering from neon in the elastic scattering channel. Satisfactory agreement between the present calculation and experimental measurements is achieved.
