Title: Precise absolute γ -ray and β - -decay branching intensities in the decay of Cu 29 67

Abstract

Absolute gamma-ray emission probabilities in the beta(-)decay of Cu-67 weremeasured by means of gamma-ray and beta(-)-decay singles and beta(-)-gamma coincidences. The new results, together with the known decay scheme of Cu-67, were used to determine absolute beta(-)-decay branching intensities. The present data differ significantly from previously published values. In addition, the half-life of the I-pi = 1/2(-) isomer in Zn-67 was measured as T-1/2 = 9.37( 4) mu s, in a good agreement with earlier measurements. From the analysis of the Fermi-Kurie plots, Q(beta-)(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 Q(beta-)(g.s.) = 561.3(15) keV recommended in the latest Atomic Mass Evaluation.
