Using the isoelectron superposition method we show that the density of autoionization states of the elements with d- and f-equivalent electrons may be from 1 to 10 states per 1 cm–1 of energy. For such elements a conception of an autoionization continuum may be introduced. The characteristic time of the resonance electrons capture are in this case comparable with the radiation time (τ ~ 10–8 s), therefore, the autoionization processes and the capture of resonance electrons result in the inversion in the ions' spectra as well as in spectra of Beitler states. The experimental results on selective autoionization and selective interaction between the ion excited states and the autoionization continuum are presented.
