摘要：

We report the observation of nuclear resonant diffraction of synchrotron radiation by a synthetic multilayer. The nuclear period of the [Fe-57(22 angstrom)/Sc(11 angstrom)/Fe(22 angstrom)/Sc(11 angstrom)] x 25 multilayer was chosen to be twice the electronic period to obtain a pure nuclear.Bragg reflection. Strong enhancement of the radiative scattering channel provided a fast time response for the Fe-57 resonant scattering at the Bragg peak, with a decay time of 4 ns. The nuclear multilayer will be useful as a narrow bandpass monochromator for synchrotron radiation.
