It is shown that the Klein–Nishina–Tamm equation determines the total intensity of coherent and incoherent X‐ray scattering. The change in the ratio of these components during the transition from scattering on a resting electron to scattering on the atomic electrons is estimated. Taking into account the innovations, the required ratio is calculated for the atom of three elements with a limited set of scattering angles. The basic expression for incoherent scattering in the Klein–Nishina–Tamm equation allows us to agree, in the first approximation, the calculated value of the total scattering intensity with the experimentally observed results. The current dependences for the intensity of coherent and incoherent x‐ray scattering on the massive multicomponent materials are presented.
