Evolution of the Rayleigh scattering from mixed Ar/Kr clusters during their saturation with krypton atoms

The evolution of the Rayleigh scattering signal from mixed Ar/Kr clusters with variation in the partial Kr concentration in the initial gas mixture is investigated. An addition of krypton in small amounts to argon is found to cause an anomalously rapid increase in the Rayleigh scattering signal amplitude, which is due to a sharp increase in the size of clusters as a result of their saturation with krypton atoms. At a partial krypton concentration above 25% in the initial mixture, the scattering signal amplitude is stabilised because of the condensation saturation during the cluster formation.
