摘要：

Diffraction enhancement of symmetry may take place in layered structures composed of two different kinds of layers, when specific conditions relative to the symmetry of the layers and mode of stacking are satisfied. The number of stacking sequences showing diffraction enhancement of symmetry for crystals having p layers of the first kind and q layers of the second kind in the repeat unit has been computed, and a method for exhibiting these sequences (enhancement cases) has been developed. Enhancement cases are presented for p + q ≤ 12. © by Akademische Verlagsgesellschaft, Wiesbaden 1979
