Abstract
The 31-yr isomer of {sup 178}Hf at excitation energy 2.446 MeV, and with J{sup {pi}}, K= 16+, 16, has been the object of several studies for possible mechanisms that might trigger isomer decay to the ground state. Potential for the control of nuclear energies (MeV) with atomic energies (keV) is the driving interest. The 178Hf isomer is a favorite nucleus in the search for triggered decay because this isomer is long-lived, available in microgram quantities, the decay scheme is well known, the excitation energy is high, and a sample enriched in the isomer can be fabricated for irradiation. In fact, accelerated decay of the {sup 178}Hf isomer when irradiated with p...
