Abstract: The applicability of the concept of scattering amplitude to the description of small-angle scattering experiments has been considered. An expression has been obtained for a scattered radiation flux on a detector under much milder conditions than the condition of Fraunhofer diffraction. The influence of incoherence of the source on the results has been evaluated.
