Abstract
A phase shift analysis of electron-neon and electron-argon scattering has been made in the elastic region. For neon, a set of s, p and d wave phase shifts consistent with the experimental data and continuous in energy is derived. The predicted phase shifts are in good agreement with theoretical values, except for the p wave, which is significantly smaller. The scattering length is found to be 0.22 a0. No consistent fit was obtained for electron-argon scattering, and within the model considered, it is suggested that the differential cross section data are inconsistent with that on total elastic and diffusion cross sections. The derived phase shifts (l=0, 1, 2, 3) agree moderately well with theoretical values, except for l=2, where the derived values are substantially smaller. The scattering length is found to be -1.65 a0, in good agreement with other determinations.
