STUDY OF THE HF-168 ELECTRON-CAPTURE DECAY

The (EC, beta(+)) decay of Hf-168, produced by the Gd-156 (O-16,4n) re action, has been studied with high efficiency HPGe coaxial detectors, using on-line measurements with the RACHEL setup. Off-line measurement s were also carried out using catcher collection technique. Energies a nd intensities of 119 gamma lines are reported among these only two we re known in the earlier study of CHU and REEDNICK. The Lu-168 level sc heme built on the basis of single gamma- and X-spectra and gamma-gamma coincidence measurements, allows the interpretation of 79 gamma-trans itions, between 38 excited states reported for the first time.
