Abstract
New approaches to the small-angle scattering data analysis for nanosized systems are presented. They are based on the application of optimization methods and a repeated solution of direct problems. Based on the new approaches the program is developed which makes it possible to simulate small-angle X-ray diffraction data, to introduce collimation corrections, and to analyze the disperse composition of samples. Results of the program performance are demonstrated for a series of typical nanosized systems (sols, catalysts) and the program is compared with the available programs for small-angle data processing.
