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
s. The corresponding B(E2) =
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.
