Electron microscopy and neutron activation techniques are used to map the elemental and isotopical compositions of ferrite bars where the emission of neutron bursts and the formation of dark regions were reported after ultrasound irradiation. Anomalous values are found in these regions. The original concentrations of natural isotopes of copper and zinc are deduced; the occurrence of pressure-induced nuclear reactions is inferred while the cavities are suggested to act as nuclear micro-reactors. The general characteristics of these phenomena are considered a support to the existence of a new type of reactions, called deformed space–time reactions (DST-reactions).
