Precision measurement of the half-life and the decay branches of 62Ga

In an experiment performed at the Accelerator Laboratory of the University of Jyvaeskylae, the β-decay half-life of 62Ga has been studied with high precision using the IGISOL technique. A half-life of T1/2=116.09(17) ms was measured. Using β-γ coincidences, the γ intensity of the 954 keV transition and an upper limit of the β-decay feeding of the 0+2 state have been extracted. The present experimental results are compared to previous measurements and their impact on our understanding of the weak interaction is discussed. (orig.)
