Nonequilibrium absorption spectra of bismuth iodide crystals in the region of the inverse hydrogen-like series (IHS) under strong optical excitation are investigated. Successive dissociation of lines in the IHS, beginning with the upper long-wavelength terms, is observed. The results are interpreted in terms of the screening of the IHS, thereby confirming the common nature of the lines.
