Abstract
The time evolution of the coherent decay of a collective nuclear excit ation (nuclear exciton), induced by 14.4 keV synchrotron radiation, wa s studied in a system of two stainless steel foils, where one was vibr ated by ultrasound (US). The US vibrations disrupted the coherent nucl ear 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.
