Description
Beta-coincident γ-rays have been measured from implanted pure samples of 12Be separated at the LISE3 spectrometer at GANIL. An intensity of 0.040(26)% can be estimated for the branching ratio of the isospin forbidden pure-Fermi transition to the 0+ excited state of 12B and of 0.008(6)% of the transition to the 1- excited state. Both are taken to represent upper limits. The half-life has been re-measured to be 26.1(2.4) ms. (orig.)
