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 Fe257O3, has been measured. The buildup from zero decay probability at time zero following excitation, increasing to a maximum 2.4 nseclater, 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.
