The theory of time dependence of inelastic Mossbauer scattering in the case of stepwise phase modulation of recoilless γ-radiation is developed. In thin scatterer approximation the theory describes the conversion electron yield for different center shift and phase change values. Inhomogeneous broadening of resonant lines and a realistic law of source motion is taken into account. Experimentally the stepwise phase modulation of the 14.4 keV resonant radiation is performed by an x-cut quartz piezotransducer to which a 57Co:Pd γ-source is cemented. By using a resonance detector with thin 57FeAl-alloy scatterers to detect conversion electrons, an acceptable time resolution (< 30 ns) is achieved. A good agreement between theory and experiments is obtained. [Russian Text Ignored.]
