Abstract
The principles of interaction of energetic electrons with atoms are reviewed with emphasis on effects due to the crystalline structure of the target. Computer "experiments" and analytic models that simulate the collision processes in a crystalline lattice are described and analyzed. The experimental part discusses, first, the techniques used for the investigation of point defects in single crystals. Then, the available experimental results on defect production and recovery in metal crystals are reviewed in detail, and basic information, such as threshold energies for displacement in the main crystallographic directions and electrical resistivities of Frenkel pairs, is extracted. Finally, it is shown how interatomic potentials can be deduced from the experimental results.
