Abstract
Polarised-orbital calculations for the low-energy elastic scattering of electrons from helium, neon and argon are presented in the adiabatic-local-exchange approximation. The polarised orbitals are calculated using a perturbed Hartree-Fock scheme and the exchange kernels in the scattering ansatz are approximated by an equivalent local potential which, for neon and argon, is constructed by augmenting Hara's free-electron-gas potential (1967) with the semiclassical approximation near the origin. In principle, all multipole moments of the electron-atom interaction are included. Partial-wave phaseshifts and scattering cross sections are presented.Keywords
