  "description": "Enhanced decay of the 31-yr isomer of 178Hf induced by x-ray irradiation has been reported previously. Here we describe an attempt to reproduce this result with an intense \"white\" x-ray beam from the Advanced Photon Source. No induced decay was observed. The upper limits for the energy-integrated cross sections for such a process, over the range of energies of 20\u201360 keV x rays, are less than 2\u00d710^-27cm^2 keV, below the previously reported values by more than 5 orders of magnitude; at 8 keV the limit is 5\u00d710^-26 cm^2 keV.",
