The structure of the [formula] surface was studied at both room temperature and a low temperature of 50 K using grazing incidence X-ray diffraction. At low temperatures diffuse scattering was observed in addition to Bragg reflection. Least squares analyses for Bragg reflections using anisotropic ...
•晶格间距dhkl与晶胞参数的关系 Principles of X-ray Diffraction X射线是1895年由德国物理学家伦琴(Röntgen)发现, 因此也叫伦琴射线。X射线是一种波长很短的电磁波 (1— 10,000pm),能量高,穿透力强,不折射不反射。 而用于测定晶体结构的X射线,波长为50—250pm,此 数值正好与晶体中原子间的数量级相当,...
LPF entries contain the ideal X-ray powder diffraction pattern calculated from the crystal structure; and they contain a complete description of the crystal structure, including crystallographic parameters and atomic coordinates, which you can use as the basis for pattern simulations and Rietveld ...
