The contribution of the thermal vibrations to the real and imaginary parts of the structure factor is discussed on the basis of experimental temperature dependences of integral characteristics for the anomalous transmission of X‐rays in germanium between 85 and 650 °K. The deviation of the temperature dependence of the imaginary part of the structure factor from the form F ih e − M ( M Debye‐Waller factor) is in good agreement with a theoretical analysis. This analysis takes into account the contributions from phonon scattering on phonons by considering a dynamic solution of the problem.
