© 2015 American Physical Society. Absolute γ-ray emission probabilities in the β- decay of Cu67 were measured by means of γ-ray and β - decay singles and β - γ coincidences. The new results, together with the known decay scheme of Cu67, were used to determine absolute β - decay branching intensities. The present data differ significantly from previously published values. In addition, the half-life of the Iπ=12- isomer in Zn67 was measured as T1/2=9.37(4) μs, in a good agreement with earlier measurements. From the analysis of the Fermi-Kurie plots, Qβ-(g.s.)=560.3(10) keV was deduced, which differs from the previously measured value of 577(8) keV but is in good agreement with Qβ-(g.s.)=561.3(15) keV recommended in the latest Atomic Mass Evaluation.
