Using the computer experiment methods directional effects of relativistic electrons’ coherent reflection from crystal surface at glancing incidence were studied in conditions when it is due to multiple transversal scattering of particles by atomic chains (axial surface channeling). Directional dependencies of backscattering coefficients, ranges and depths of reflected electrons’ penetration in crystal and their angular distributions have been calculated. It has allowed to elicit the directional effects of strings that lead to reflection at grazing angles close to the beam incident angle with respect to atomic chain as well as kinetic effects of surface plane that result in specular reflection and dominate at large beam misalignments with respect to low-index crystallographic directions.
