利用同步辐射的核共振散射首次观测到了α-Fe多晶薄膜的声子能谱。测量的能谱与早先的中子非弹性散射数据符合得很好。这种方法的优点之一是只可能激发特定的元素。结果表明，该方法适用于晶格动力学的研究，开辟了核共振散射光谱的新领域。
The phonon energy spectrum of a polycrystalline α-Fe foil was observed via nuclear resonant scattering of synchrotron radiation for the first time. The measured spectrum is in good agreement with earlier neutron inelastic scattering data. One of the advantageous features of this method is that excitation of only a specific element is possible. Our results show that this method is applicable to the study of lattice dynamics and open a new field of nuclear resonant scattering spectroscopy.
