Abstract

The radiation of very high energy (≈ 100 GeV) electrons and positrons in crystals is greatly enhanced when the particles are directed parallel to a crystal axis. The pair creation by photons of a similar energy is also enhanced by alignment with a crystal axis. The enhancement is produced bv the crystal's strong electric field. For alignment, the incident particles are subject to a roughly constant field for a sufficiently long time to allow field-induced quantum electrodynamic (QED) processes to take place. In many instances, semiclassical QED can accurately predict the enhanced radiation and pair-creation rates. We review this semiclassical theory, examine its advantages and limitations, and compare theoretical results with experiments.
