Title: Calculations for electron-impact ionization of magnesium and calcium atoms in the method of interacting configurations in the complex number representation,
Abstract: Next investigations in our program of transition from the He atom to the
complex atoms description have been presented. The method of interacting
configurations in the complex number representation is under consideration. The
spectroscopic characteristics of the Mg and Ca atoms in the problem of the
electron-impact ionization of these atoms are investigated. The energies and
the widths of the lowest autoionizing states of Mg and Ca atoms are calculated.
Few results in the photoionization problem on the autoionizing states above the
n=2 threshold of helium-like Be ion are presented.
