A modification of resonance amplitudes is proposed that takes into account violent inner-shell processes accompanied by correlated multielectron transitions. For light ions with electrons in high Rydberg states, the conventional expression for the total widths of the resonance states given in terms of the Auger and radiative transition probabilities is not adequate. The present terms introduced to the widths can be very large and can seriously affect dielectronic recombination and resonance excitation; all the earlier calculations have been reexamined. Implications of this change on future calculations and on other related processes, such as photoionization plus Auger ionization, excitation-autoionization, multiple ionization, and similar processes in ion-atom collisions are also discussed.
