利用核退激辐射通道研究了同步辐射与119 Sn核的非弹性散射。测量了23.8795 keV X射线被$\ensuremath{\beta}$-Sn箔核散射的能量依赖性，能量分辨率为亚meV。在实验条件下，散射在各种原子核上是不相干的，并在声子动量转移上平均。实验数据与核非弹性吸收理论进行了比较。总体一致是合理的，但也注意到一些偏差。的差异的可能来源进行了讨论。
We have investigated inelastic scattering of synchrotron radiation by ${}^{119}\mathrm{Sn}$ nuclei using the radiative channel of nuclear deexcitation. The energy dependence of nuclear scattering of the 23.8795-keV x rays by a $\ensuremath{\beta}$-Sn foil was measured with sub-meV energy resolution. In the conditions of the experiment the scattering was incoherent over the various nuclei and averaged over the phonon momentum transfer. The experimental data are compared with the theory of nuclear inelastic absorption. The general agreement is reasonable, however, some deviation is noted. The possible origin of the discrepancy is discussed.
