A generalization of the viscoelastic model to binary systems has been applied to analyze inelastic X-ray scattering spectra from a He{sub 0.8}Ne{sub 0.2} mixture. Experiments have been carried out at temperature T = 82 K and number density n = 18.5 nm{sup -3}. In order to test the reliability of such a generalization, we measured a few representative spectra. The model exhaustively describes the experimental data and provides a determination of the spectral densities of the separate mixture components as well as those of both density and concentration fluctuations. These results can be considered as a first test for further developments.
