已经测量了多晶铁箔（同位素富集和天然丰富）同步加速器辐射的延迟相干核前向散射。 在时间谱中观察到量子拍。 在选定的实验条件下，这些只能由相干散射产生。 特殊的硅晶体单色仪提供 5-meV 带宽，无需使用核谐振滤波器。 这种直接方法提供了使用同步加速器辐射进行广泛的穆斯堡尔光谱实验的可能性。
Delayed coherent nuclear forward scattering of synchrotron radiation by polycrystalline Fe foils (both isotopically enriched and naturally abundant) has been measured. Quantum beats were observed in the time spectra. With the chosen experimental conditions these can only arise from coherent scattering. The 5-meV bandwidth provided by a special silicon crystal monochromator obviates the need for a nuclear resonant filter. This direct approach offers the possibility of performing a wide range of Mossbauer spectroscopy experiments using synchrotron radiation.
