Abstract
The work considers the application of laser correlation spectroscopy to the investigation of dispersed systems for such a case, which can be regarded as a transitional to the multiple scattering regime. It is shown that even a slight violation of the condition of single scattering by the increasing of concentration of scattering centers can affect the result of particle size measurements. It should be taken into account when studying colloids.
