Search for X-Ray Induced Acceleration of the Decay of the 31-Yr Isomer of H
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--60keV x rays, are less than 2 x 10-27 cm2keV, below the previously reported values by more than 5orders of magnitude; at 8keV the limit is 5 x 10-26 cm 2 keV
