Abstract
We have measured the angle and concentration dependence of the first cumulant of the field-correlation function for multiply scattered light from polystyrene latex particles in water. The experimental results are analyzed in terms of a model based on the assumptions that the scattering particles are pointlike and that the number of renormalized scattering events is Poisson distributed. The agreement between theoretical and experimental results is satisfactory.
