摘要：
The feldspar mineral Labradorite exhibits a long-range superstructure of 1500 Angstrom period length, and corresponding s-satellites up to 4th order are observed in X-ray diffraction experiments with enhanced resolution. By analyzing the satellite-profiles along the direction of the modulation, imperfections of the lamellar superstructure are investigated. The measured profiles are successfully reproduced by a model based on Laue-functions, and an average roughness of the lamellar interfaces of 330 Angstrom is obtained.
