Angular correlation of the 1.07-1.24 MeV gamma cascade in the decay of Ga<SUP>68</SUP>

We have measured the angular correlation of the 1.07-1.24 MeV gamma-ray cascade in Zn68 following the decay of 68-min Ga68. The Legendre polynomial expansion coefficients were determined to be A2=0.31&#177;0.03 and A4=0.23&#177;0.07. The measured correlation establishes the spin sequence to be 2-2-0, with a quadrupole-dipole mixing ratio &#948; of +1.8&#177;0.2 for the 1.24-MeV gamma-ray. The result of the angular correlation work together with the allowed nature (log ft = 5.7) of the electron-capture decay to the 2.3-MeV level fixes the spin and parity of this level to be 2+. The results are consistent with the near-harmonic model of Scharff-Goldhaber and Weneser for even nuclei
