The application of the indirect Fourier transformation method and the square‐root deconvolution procedure of Glatter [Glatter (1977). J. Appl. Cryst. 10 , 415–421; Glatter (1981). J. Appl. Cryst. 14 , 101–108] for a determination of the cross‐section structure of cylindrical and polymer‐like micelles is investigated. The data analysis methods assume: (i) the rod‐like structures are infinitely long and straight; (ii) the particles have cylindrical symmetry; (iii) the particles are monodisperse in the cross‐section size and have no fluctuations in the cross‐section structure. The influence of the violations of these assumptions on the applicability of the methods and the limitations have been investigated by analyzing series of simulated scattering data. In addition, the influence of finite range of scattering vectors for the data and the presence of diffuse correlations along the rod‐like particles have been determined.
