Popis: 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.
