Biava, D A; Saha, H P; Engel, E; Dreizler, R.M.; McEachran, Robert; Haynes, M.A.; Lohmann, Birgit; Whelan, C T; Madison, Don Harvey


First order distorted wave Born approximation (DWBA) triple differential cross sections are reported for low-energy electron-impact ionization of the inner 3s and outer 3p shells of argon. Previous DWBA works have demonstrated that experiment and theory are not in accord for low energy ionization of inert gases and here we investigate the importance of exchange scattering. Different approximations for treating exchange scattering are investigated. It is shown that exchange scattering is...[Show more]
