The decay of 74Kr has been studied. Its half-life was determined to be T 1 2 = 11.50 0.11 min. A decay scheme is proposed, based on - and +- coincidence measurements, which takes account of 99 % of the strength of 57 observed -rays. The total decay energy was measured to be QEC = 3327 125 keV. The decay feeds the (0, 1)-, T 1 2 = 25.3 min isomer of 74Br. 1975.
