Abstract

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 $T_{1 ∕ 2} = 116.19 (4) ms$ . 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 $116.18 (4) ms$ .
