Annotation
The Hartree-Fock approximation is used to study the 3d photoabsorption in the near-threshold region for the following atoms and ions: $I^-, Хе, Cs^+, Ва^{2+}, La^{3+}$. We discuss the hypothesis of 4f-state collapse in the isoelectronic series of Xe. It is shown that the features of the absorption cross section in $Cs^+$ can be explained without invoking the hypothesis of 4f-state collapse.
