Energy-dependent polarization potential, dispersion-relation absorption potential, and matrix effective potential for electron-neon scattering at 10 — 100 eV

We report model-potential calculations of the elastic and absorption cross sections for $e-\mathrm{Ne}$ scattering at 10, 30, 50, and 100 eV. Altogether nine different model potentials are studied; these include the variational matrix-effective-potential method, an absorption potential calculated ab initio from a real energy-dependent polarization potential and a dispersion relation, and two different phenomenological absorption potentials. We get good agreement with experimental results by several methods at 30 — 100 eV and by one method at 10 eV. The tests of the various methods establish useful trends and expectations for future work.
