The β -decay half-life of 62 Ga has been studied with high precision using on-line mass separated samples. The decay of 62 Ga which is dominated by a 0+ to 0+ transition to the ground state of 62 Zn yields a half-life of T1/2 =116.19(4) ms . This result is more precise than any previous measurement by about a factor of 4 or more. The present value is in agreement with older literature values, but slightly disagrees with a recent measurement. We determine an error-weighted average value of all experimental half-lives of 116.18(4) ms .
