The beginning of the application of the method of interacting configurations in the complex number representation to the compound atomic systems has been presented. The spectroscopic characteristics of the Be atom in the problem of the electron-impact ionization of this atom are investigated. The energies and the widths of the lowest 1 S, 1 P, 1 D, and 1 F autoionizing states of Be atom are calculated.

“…The reason is in the long-range property of Coulomb potential and, as a consequence, in the slow convergence of the corresponding series. Therefore, usually the method is applied for the simplest atomic systems [78][79][80]. As an example, the method was applied for the (e, H) system, in which the hydrogen negative ion bound state and the lowest members of the resonances in both the singlet and the triplet J = 0 series were calculated [78].…”

The transition from the He atom to the complex atoms description in the method of interacting configurations in the complex number representation has been presented. As a first step the problem of ionization of H − and Li + ions is considered. The spectroscopic characteristics of the Be, Mg and Ca atoms in the problem of the electron-impact ionization of these atoms are investigated. Few results in the photoionization problem on the 1 P autoionizing states above the n=2 threshold of helium-like Be ++ ion are presented. The energies and the widths of the lowest 1 S, 1 P, 1 D, and 1 F autoionizing states of the Be, Mg atoms, and the lowest ( 1 P ) autoionizing states of Ca atom, are calculated. We consider briefly both a review of our previous results (together with results of other authors) and new calculations of our group. A brief review of the methods of the quasi-stationary states calculation is given.
