Abstract: A method for searching for parameters of structural models of weakly ordered thin films based on X-ray diffraction data containing a small number of reflexes is proposed. The developed method makes it possible to narrow down the number of possible structural models, despite the small number of interference maxima, determine the parameters of possible elementary cells and index the corresponding peaks on diffractograms. It is shown how the use of a priori data makes it possible to obtain physically adequate solutions. The method of determining structural parameters is demonstrated by analyzing an experimental curve containing only 3 diffraction peaks (maxima). The corresponding search algorithms are implemented within the framework of the analytical software package BARD (Basic Analisys of xRay Diffraction).
