Abstract

Expressions for the energy and angle dependent cross section for channeling radiation are given in the nearly-free electron approximation. General selection rules are also given, and the nature of the allowed transitions is described on the dispersion surfaces of high energy electron diffraction. An interpretation of the radiation in terms of 'extinction distance wiggling', consistent with the theory of the free-electron laser, is given. The crystal structure information in channeling radiation spectra is elucidated.
