A method is proposed for determining the density of one-phonon states, which is based on determination of the shape of the vibrational spectrum of an isotopically mixed crystal. Its correctness is experimentally verified by analyzing the spectra for Raman scattering of light (RSL) in the Nal5N*4N, _ x03 crystals.
