Determination of Q Values for Electron-Capture Decay of 172Hf and 188Pt from X-Ray Intensities

Q values for electron-capture decays are not directly measurable. One must instead rely on indirect methods. One such technique utilizes x-ray intensities and/or transition intensities obtained from coincidence measurements. In these instances, the accuracy of the deduced energies depends on the correctness of the decay schemes and of theoretical capture ratios. We have applied this technique in the determination of QE.C for 172Hf and 188Pt.
