中文摘要

当一束细小的X射线射向晶体时,X射线只在特定的角度被反射。在这些角度中的每一个角度处反射光束的强度变化,并且强度取决于晶体中原子的排列。考虑到反射的X射线的所有强度,就有可能算出晶体中所有原子的排列。X射线实际上被每个原子周围的电子反射。大多数电子都聚集在原子中心附近的电子云中(核心电子),但少数远离原子中心的电子与相邻原子的电子云相互作用。这种相互作用产生了吸引力,使原子在分子中聚集在一起。
英文摘要
When a fine beam of X-rays is directed at a crystal, the X-rays are reflected only at specific angles. The intensity of the reflected beam at each of these angles vary and the intensity depends on the arrangement of the atoms in the crystal. It is possible to work out the arrangement of all the atoms within a crystal from a consideration of all the intensities of the reflected X-rays. The X-rays are actually reflected by the electrons around each of the atoms. Most of the electrons are held in a tight cloud close to the centre of the atom (the core electrons), but a few electrons, further away from the atom centre interact with the electron clouds of adjacent atoms. This interaction creates the attraction which holds the atoms together in a molecule.
