摘要：

We report on the observation of radiation trapping in resonant scattering of 14.4 keV x rays by Fe-57 nuclei. Spatially incoherent excitation of nuclei was prepared by a short pulse of synchrotron radiation. The time evolution of the scattered radiation showed an exponential decay with the decay time longer than the natural lifetime. The results agree with the calculations based on the model of multiple spatially incoherent nuclear resonant scattering.
