APPLICATION OF A LAPLACE TRANSFORM METHOD TO THE STUDY OF BINARY-MIXTURES OF SPHERICAL AND ROD-LIKE PARTICLES FOR LOW-INTENSITY LEVELS

A Laplace Transform (LT) method is used to improve the results obtained in a quasi-elestic scattering (QELS) experiment. This is designed to determine the characteristics parameters of a bimodal solution of spherical and rod-like macromolecules. The theoretical study and the experimental simulation are carried out for low light levels, and the results show that the LT technique provides a real alternative to the second order correlation function, g(2)(tau), in QELS measurements for these particularly difficult experimental conditions.
