Analysis of photon correlation spectral decay functions. Part 4.—Bimodal polydisperse systems

Abstract

The S-exponential sum method has been applied to the analysis of bimodal polydisperse scattering systems. The method has advantages in not requiring prior knowledge of the data accuracy and does not assume a parametrised form for the polydisperse distribution. The accuracy for the derived moments of the distribution is limited only by the accuracy and noise content of the data set, and the method is able to derive correct moments for the distribution.
