The introduction of the effective integral quantities characterizing non‐homogeneous particles and their volume fraction leads to an expression for the distance distribution function analogous to that for homogeneous particles. This significantly simplifies the determination of the structure characteristics of particles. The procedure is outlined for obtaining the distribution of excess electrons and the total number of electrons within the particle from relative SAXS b) intensity data. The mode of the spatial arrangement of the partially ordered system of particles can be estimated by comparing the characteristic numbers calculated for different structure types with that characteristic number determined from relative intensities, namely from the effective quantities of the system and from the position of the maximum of interference function.
