Abstract
By inelastic neutron scattering we determine the dynamic structure fac tor S(k, co) of a dense He-Ar ps mixture. S(k, omega)) is the sum of t wo Gaussians in frequency omega with halfwidths omega(H)Ar(k) much les s than omega(H)He(k) the decay rates of fluctuations in the density of Ar and He atoms. The results agree with the Enskog theory.
