Energy emissions from resonant cylindrical samples subjected to ultrasound vibrations

This paper discusses the phenomenon of energy emissions from brittle specimens subjected to resonant ultrasound vibration. The aim is to describe and demonstrate the neutron emissions from piezonuclear reactions that have been recently observed for the first time and published in [1-3], providing new experimental evidences. In addition to some natural brittle rocks, as considered in the previous studies, sintered ceramic samples are studied. The energy release during ultrasound vibration is assessed by continuously monitoring the electric power input, the temperature of the specimen, as well as the neutron emission by means of He3 devices and bubble detectors. As a result, the energy balance can be estimated, suggesting that an extra energy amount is generated due to the piezonuclear phenomena involved.
