In this paper we present the first theoretical study of the coherent Rayleigh–Brillouin scattering in binary mixtures of monatomic ideal gases. The line shape of the coherent spectrum is determined by solving a kinetic model of the Boltzmann equation that replaces the collision operators by simple relaxation-time terms which are compatible with the two-fluid hydrodynamic theory. Theoretical predictions for the coherent light scattering spectrum in dilute argon–krypton gas mixtures are presented and its dependence on concentration and pressure is analysed.
