Quantummechanical treatment of highenergy channeling radiation

 An alternative theoretical description of axial electron channeling in the multiGeV region has been developed. We solve a kinetic equation to evaluate an electron distribution function in axially oriented single crystals. Based on the singlestring model, the required matrix elements for radiation and scattering by lattice vibrations are calculated employing solutions of the Dirac equation in cylindrical coordinates. Results obtained for 150GeV electrons propagating along the 〈110〉 axis of germanium are in good agreement with experimental observations.
