Abstract
An exact expression for the diffusion coefficient of two-component gas with an arbitrary dispersion law and statistics is obtained. Various limiting cases are considered. The limits of the diffusion coefficient variations are found. The diffusion coefficient is shown to be depend ent on the relaxation rate of particles of the same type. As an exampl e, the roton-impuriton system of superfluid helium isotope mixtures is considered.
