A process of radiation destruction in germanium crystals, generated by 100-kev electron bombardments, has been studied. The K-shell ionization cross section is given, and the assumption is made that the crystal thickness is much smaller than the electron mean free path. An expression is derived for the concentration of probable pair distribution of ionized atoms and eventually of the atom concentration displaced by a single electron. It is shown that in valence crystals, with sufficiently low hole mobility, the mechanism of the formation of displacements is even more effective when associated with valence electron transfer and outer shell ionization.
