It is shown that the analytical form of some characteristics of the anomalous transmission of X‐rays for divergent incident beam is different from the corresponding expression derived for the case of parallel beam. In particular, the expressions for the reflection coefficient and half‐width are modified, while the integrated intensity preserves the same meaning. The new content of the reflection coefficient makes it possible to use it for obtaining the integral characteristics of anomalous transmission, connected with different parts of the structure factor. Consideration of the divergence of the incident beam leads to a good agreement of the experimental and theoretical data for the characteristics of anomalous transmission.
