The Study of 175Hf Decay
Section: Nuclei and Nuclear Reactions
Original Author's Text: Ukrainian
The intensities of lines of the internal conversion electron and γ-rays emitted at the decay of 175Hf nucleus (T1/2 = 70 days) have been measured with the help of a π√2 magnetic β-spectrometer and two coaxial HPGe-detectors. On the basis of those data, the β-ray branching ratios and the log ft values for β-transitions are calculated. The limits on the log ft values for β-transitions to 175Lu levels 9/2+ at 113.8 keV, 9/2- at 396.3 keV, and 9/2+ at 546.6 keV have been found for the first time.
Key words: radioactivity, 175Hf, γ-spectrum, HPGe-detector, internal conversion, magnetic spectrometer, intensity measurements.
