ABSTRACT:
In the method of this invention, a radioactive isotope, for example, U.sup.238, is placed within a region. High-energy electrons or high-energy photons in the form of X-rays, gamma rays, or laser excitation are applied to the region. This energy is absorbed by the nucleus of the isotope, placing the nucleus in an excited state. Upon relaxation, the nucleus ejects a neutron, or neutrons, through the gamma-neutron reaction, resulting in a product isotope, namely U.sup.235.
