Angular distributions of Diffracted Channeling Radiation from moderate energy axially channeled electrons in Si and LiF crystals

Numerical calculations of the Diffracted Channeling Radiation angular distributions from axially channeled electrons with relativistic factor γ = 20 in Si and LiF crystals are performed. The calculations are based on a newly developed effective quantum-mechanical calculations algorithm of the wave functions and electron energies at axial channeling in a crystal. The numerical results obtained exhibit some new features of the Diffracted Channeling Radiation from axially channeled electrons compared to that from planar channeled electrons, e.g. increase of the widths of peaks, which might be useful in future experiments on observation of Diffracted Channeling Radiation.
