K-absorption structures were calculated for Ne, Na and Ar within the region of photo-double excitation/ionization. Ionization cross section were calculated using the theory of non-orthogonal orbitals and the energies were obtained via configuration interaction method. Calculated spectra are in good agreement with the experiment. It is shown that to describe photoionization probabilities it suffices to take into account the monopole rearrangement of electron shells. In order to interpret the fine structure of the experimental spectra one must consider angular correlations in the movement of both core and excited electrons as well as the fact that the single and multiple ionization channels open at specific energies.Nous avons calculé la stru...
