Abstract

The method of interacting configurations in complex number representation (MICCNR) is applied to the problem of electron impact ionization of Be atom. The energetic positions of the lowest 1 S, 1 P, 1D autoionizing states are obtained. The comparison of our data with energies of similar states, which are formed in the problem of the scattering of electrons by the Be ion, is carried out.
