Abstract
The half-life of the first excited state of 64Ga has been measured with a pulsed beam technique. The half-life was determined to be $T\sb{1/2} = 21.9 \pm 0.7
\mu$s. The corresponding B(E2) = $13.6 \pm 0.4$ e2fm4 shows good agreement with the Weisskopf estimate, i.e., 15.2 e2fm4, thereby establishing the 2+assignment to this state and the single particle nature of the 42.89 keV transition.
