Abstract

The scope of this chapter is outlined in Section 4.2.1. The next section, Section 4.2.2, presents a summary of basic scattering theory containing general scattering formulae and formulae for cross sections. Section 4.2.3 discusses a general treatment of disorder diffuse scattering and describes the basic mathematics and general qualitative formulation of disorder. Occupational disorder, displacive disorder, domain disorder and lamellar disorder are discussed and guidelines for solving a disorder problem are given. Section 4.2.4 describes quantitative interpretation and covers quantitative solutions and methods for treating disorder problems in layered structures (one‐dimensional stacking disorder), structures with chain‐like elements (two‐dimensional disorder), defect structures, short‐range ordering, clustering, molecular crystals and orientational disorder. The last section, Section 4.2.5, describes experimental methods for measuring diffuse scattering.
