In an experiment performed at the Accelerator Laboratory of the University of Jyväskylä, the beta-decay half-life of the 62Ga has been studied with high precision using the IGISOL technique. A half-life of T1/2 = 116.09(17) ms was measured. Using beta-gamma coincidences, the gamma intensity of the 954 keV transition and upper limit of the beta-decay feeding of the O_2+ state have been extracted . The present experimental results are compared to previous measurements and their impact on our understanding of the weak interactions is discussed.
