20190170896 · 2019-06-06 ·

An excitation transfer in a nuclear state is energetically induced. The excitation transfer may be induced by heating a structure to which a nuclear species is mechanically coupled. The heating may be applied as a triangular heat pulse. The heating may generate a stress effect in the structure. The stress effect may produce vibratory phonons. The excitation transfer may include up-conversion. The excitation transfer may include radioactive decay. The decay rate of a radioactive species may be increased to a rate higher than the natural half-life of the radioactive species. Energy may be harnessed from decay of the radioactive species. A decay product having industrial or medical use may be rapidly produced. The decay rate of the radioactive species may be lowered to reduce emissions for safe storage or transportation.
