本文报道了同步辐射脉冲激发的原子核相干散射辐射中的量子拍频现象。测量是用Fe 57富集的钇铁石榴石晶体，通过使用纯核（002）布拉格反射从两个平行晶体的反射。由此产生的拍频模式提供了一个灵敏的直接测量单个铁核的超精细分裂，以及不同核位置之间的能量转移。
We report the experimental observation of quantum beats in the coherently scattered radiation from nuclei excited by synchrotron-radiation pulses. The measurements were made with Fe 57-enriched yttrium-iron-garnet crystals, by reflection from two parallel crystals using the pure nuclear (002) Bragg reflection. The resulting beat pattern gives a sensitive direct measure both of the hyperfine splittings of individual iron nuclei, and of the energy shifts between different nuclear sites.
