The elastic scattering of electrons by nitrogen, neon, phosphorus and argon atoms

Results are presented for the elastic scattering of electrons by nitrogen and phosphorus atoms in the energy range 0-1 ryd, and by neon and argon atoms in the energy range 0-4 ryd. Calculations have been carried out in a single state approximation but include both exchange and polarization effects. The polarization potential has been determined using the polarized orbital method of Temkin. Results are in good agreement with experiment for neon and argon but it is found that the single state approximation is not sufficient for a correct representation of the nitrogen 3 P resonance.
