摘要：
Specific features of electromagnetic showers in crystals initiated by electrons with energies of a few GeV are considered, basing on a model form of radiation spectrum at axial alignment Formulae describing the influence of ordered crystalline structure on incoherent processes are derived, using Yukawa potential for a separate atom. Positron yield from crystal and amorphous targets for the kinematics inherent in positron sources is calculated, showing definite advantages of crystals.
