It is shown that resonance scattering introduces an important contribution to the broadening and displacement of the Rydberg series in atoms and explains the presence of oscillations. Analysis of the experimental data permits the reconstruction of the binding energy of the quasidiscrete level for a negative ion, its autoionization width, orbital angular momentum, and its multiplicity.
