Ionization of the 3p orbital of argon by 113.5 and 200 eV incident electrons is studied by means of the postversion of the CDW-EIS model. Results are presented for 2, 5, and 10 eV ejected electrons and compared torecent experimental data from Lohmann and collaborators. The present results are also compared to thoseobtained by other state-of-the-art theoretical methods. The present system is extremely sensitive to the way inwhich the post-collision interaction, the electronic exchange and the initial state correlation are considered. Weconclude that none of the here discussed methods provides an ultimate description of the system and furthertheoretical work is needed.
