We find that our models CPE4 and DW2 give results which are in fair agreement with the experiments. Both models contain a final state representation which includes the electrostatic repulsion between the ejected electron and the scattered electron.enAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/Atomic, molecular and optical physicsPhysical sciencesTotal cross sections for the ionization of atoms through electron impactDistorted-wave approximationArticle
