Coherent transient effects have been observed experimentally during the stepped phase modulation of a 57Co(Pd) γ source by means of a piezoelectric transducer. The effects take the form of periodic pulses in the intensity of the 14.4-keV resonant γ radiation transmitted through the absorber. The pulses have a short rise time (15-30 ns), a length less than 100 ns, and a peak intensity exceeding the steady-state level of the resonant effect. The use of these coherent transient effects to study the time evolution of inelastic resonant scattering is demonstrated.
