Abstract
The model of dynamic scattering on a finite ensemble of Brownian particles in liquid is considered. It is shown that an artifact characteristic relaxation time appears in the autocorrelation function of the scattered light intensity, which is much longer than the correlation time controlled by particle diffusion in the scattering volume.
