Abstract: The possibilities of application of spectral dependence of light scattering dissymmetry (Z) in distributional analysis of polydispersions with spherical particles are described. The calculation of the best estimates of distribution function parameters and the estimate of standard deviations were performed numerically using the Simplex method. For theoretical computations of light scattering characteristics the exact Lorenz-Mie theory was applied.The algorithm of the numerical search of distribution parameters was tested on the experimental values of Z of polystyrene latexes from literature. The best estimates of the median and breadth parameters determined were in very good harmony with the results from literature.
