Paper Abstract

The time-delayed scattering in 14.4 keV Mossbauer resonance at 57 Fe has been intensively studied using pulsed synchrotron radiation source and delayed coincidence technique. Here, results of x-ray interferometric experiments are shown, which were obtained at KEK with this nuclear resonance. There, the interference arises from the beams re-emitted by different nuclei with some time interval after the absorption of a single incident photon. High visibility interference oscillations verified the coherent superposition as well as the complete coincidence in the time domain of the beams after the nuclear resonance. The collective nuclear excitations from a single photon are discussed with regard to the no-reduction of the detection probability. In addition, the phase information transfer in successive absorption and re-emission with time-delay, and the dispersion effect at the nuclear resonance are shown.
