【 摘 要 】

The problem of a dynamic diffraction of a plane monochromatic X-ray wave at the absorbing superlattice with a stacking fault between the layers for the trapeziform model of superlattice is considered. It is shown, that presence of stacking fault reduces the anomalous absorption. The interference absorption depends on the shift vector and depth of the stacking fault and the structural factor of superlattice.
