ABSTRACT
Electron crystallography is an important technique for the determination of unknown crystal structures, complementing x-ray and neutron diffraction. The birth of electron crystallography dates back to the discovery that electrons possessed both particle and wave properties. The crystallographers Pinsker, Vainshtein, and Zvyagin solved inorganic crystal structures from electron-diffraction patterns, notably texture patterns (1-3). They designed and used their own electron-diffraction cameras and quantified electron-diffraction intensities and treated them kinematically. In spite of this early start in 1947, electrons have not been used much for crystal-structure determination outside Moscow until the last two decades. Unfortunately, the development of electron crystallography for the study of inorganic crystals was long hampered by an exaggerated fear of dynamical effects.
