The Electron Microscope as a Crystallographic Instrument
Of all the possible scattering methods capable of resolving interatomic distances, only those employing electrons permit the relationship between an object and its diffraction pattern to be directly visualized. This is because the paths of electrons can be changed by a magnetic field without a change in their energy; hence electron lenses exist and, therefore, electron microscopes can be constructed (see, e.g., Reimer, 1984).
