We analyze the data reported in the literature on the time variation of the 14.4 keV Fe-57 line induced by the emission of Co-57. An anomalous decay of Co-57 was observed in the presence of ultrasound sonication. In this study, we investigate this behavior within the framework of Deformed Space-Time (DST) theory and deduce that only a fraction of an ultrasound cycle is sufficient to produce this anomaly.
