[en] Calculations of triple differential cross sections for the process where impact of a moderately energetic electron on a two-electron target simultaneously ejects one of the electrons and excites the other are made in the framework of a first Born approximation without exchange. Results obtained using ejected electron wavefunctions calculated with Coulomb potentials of different effective charge, with the static potential due to the unperturbed residual ion, or with Klapisch-type parametric potentials, are compared with experimental data.
