Precise absolute -ray and -decay branching intensities in the decay of
Abstract
In this work, absolute γ-ray emission probabilities in the β- decay of 67Cu 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 67Cu , 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 = 1/2- isomer in 67Zn was measured as T1/2 = 9.37(4) μs, in a good agreement with earlier measurements. Lastly, 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.
