The (EC, β + ) decay of 1 6 8 Hf, produced by the 1 5 6 Gd ( 1 6 O,4n) reaction, has been studied, with high efficiency HPGe coaxial detectors, using on-line measurements with the RACHEL setup. Off-line measurements were also carried out using catcher collection technique. Energies and intensities of 119 γ-lines are reported among these only two were known in the earlier study of Chu and Reednick. The 1 6 8 Lu level scheme built on the basis of single γ- and X-spectra and γ-γ coincidence measurements, allows the interpretation of 79 γ-transitions, between 38 excited states reported for the first time.
