A combined application of resonant Bragg diffraction by a nuclear multilayer structure and specular antireflection by a coating film to provide a beam of synchrotron radiation with super narrow, ΔΕ/Ε= 10~u, bandwidth has been studied. A proposed structure includes two antireflecting films above and below the nuclear multilayer. Computer simulation shows that a high nuclear reflectivity with a suppression of electronic scattering down to 4x 10~7 at the angular position of nuclear Bragg reflection can be attained.
