Coherent X-radiation generated by relativistic elektron along its velocity in periodically lavered medium

Abstract

Dynamic theory of coherent X-radiation generated by relativist.ic electron crossing multilayered medium is developed. It is found the radiation along the electron velocity vector in Bragg’s scattering geometry for general asymmetric case. The comparison of analogous radiation generated by relativist.ic electron in the single crystal medium is done. The developed theory predicts some conditions under which this coherent, radiation exists and also it describes its spectral and angular characteristics
