vVe have measured the angular correlation of the 1.07 -1.24 MeV gamma-ray cascade in Zn GS following the decay of 68-min Ga ss. The Legendre polynomial expansion coefficients were determined to be A~= 0.31±0.03 and A 4 = 0.23±O.07. The measured correlation establishes the spin sequence to be 2-2-0, with a quadrupole-dipole mixing ratio 8 of +1.8±0.2 for the 1.24-MeV gamma-ray. The result of the angular correla.tion work together with the allowed nature (log It = 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.
