Peculiarities of critical light opalescence in a spatially limited multicomponent system

The light scattering by a spatially limited liquid multicomponent system near its critical state is investigated. A radially symmetric system is considered. The pair correlation functions of the density fluctuations of the components, on the basis of which the intensity of the single scattering of light is analyzed, are calculated for this system. It is shown that the light scattering in spatially limited multicomponent systems can be studied within the framework of approaches used for single-component and binary mixtures.
