摘要：

For the first time nuclear Bragg diffraction of synchrotron radiation at the 8.41 keV resonance of Tm-169 was observed. Time differential measurements were performed with the pure nuclear (424) reflection of a thulium iron garnet single crystal. The dynamical theory of Mossbauer optics is applied to evaluate the time spectra. The measurements reveal information about the hyperfine fields which has not been accessible before by conventional Mossbauer spectroscopy with polycrystalline samples.
