The full time evolution of the coherent deexcitation of the 14.4-keV nuclear resonance, excited by synchrotron radiation in a single crystal of the simple antiferromagnet /sup 57/Fe/sub 2/O/sub 3/ has been measured. The buildup from zero decay probability at time zero following excitation, increasing to a maximum 2.4 nsec later, has been observed experimentally for the first time. The results are in good agreement with calculations based on the dynamical theory of nuclear Bragg scattering.
