The time evolution of the coherent decay of a collective nuclear excitation (nuclear exciton), induced by 14.4 keV synchrotron radiation, was studied in a system of two stainless steel foils, where one was vibrated by ultrasound (US). The US vibrations disrupted the coherent nuclear emission from the two targets. However, at times corresponding to multiples of the US period, spike increases in the decay were observed. The spikes are interpreted as echoes of the initial nuclear exciton. {copyright} {ital 1996 The American Physical Society.}
