We report a study of the decay of 62Ga, whose dominant branch is a superallowed 0+ 0+ transition to the ground state of 62Zn. We find the total half-life to be 115.84 0.25 ms. This is the first time that the 62Ga half-life has been measured with a purified source. We find that (0.1200.021)% of the decays are followed by cascades that pass through the 62Zn 2+ first excited state at 0.954 MeV. The branching ratio to the first-excited 0+ state in 62Zn at 2.33 MeV is <0.043%. We conclude that the branching ratio for the super-allowed transition is 99.85-0.15+0.05%.
