摘要：

The peaks in X-ray diffuse scattering associated with the diffraction of the incident or scattered waves from a periodically layered structure are investigated analytically and compared with numerical calculations. It is shown that if the roughness of the periodic interfaces is uncorrelated, the peaks follow the intensity of the X-ray standing wave at the interfaces. Interference effects due to correlated interfacial roughness can change the sense of the peak (sequence of maximum and minimum). The factors controlling the peak sense are derived and applied to explain the results of numerical calculations.
