Initial search for triggered gamma emission from Hf-178(m2) using the YSU miniball array.

Original language description

Experiments with the long-lived, high-K isomer Hf-178(m2) have been recognized as intriguing tests of multi-quasiparticle state structures and their interactions with external radiation. A triggered release of the energy stored by this isomer, 2.5 MeV per nucleus or 1.2 GJ/gram, in the form of a gamma-ray burst might prove valuable for numerous applications. The observation of 'accelerated' decay of Hf-178(m2) during irradiation by 90-keV bremsstrahlung has already been reported, but with poor statistical accuracy due to the experimental approach. That approach employed single Ge detectors to seek increases in the areas of peaks at energies corresponding to transitions in the spontaneous decay of the isomer. The need for better quality data to confirmthose results has motivated the development of improved detection concepts. One such concept was utilized here to perform an initial search for low-energy (< 20 keV) triggered gamma emission from Hf-178(m2) using the YSU miniball detector
