• The decay of Ga^<68>(68 min) has been investigated with beta- and gamma-ray scintillation spectrometers. Two beta-ray components with endpoint energies of 1.95±0.03 MeV, and 0.88±0.05 MeV are observed. Gamma-rays of 0.80±0.02, 1.08±0.01, 1.24±0.02 and 1.88±0.01 MeV are confirmed. Angular correlation of the 1.08-0.80 MeV gamma-ray cascade in Zn^<68> have been measured. The Legendre polynomial expansion coefficients are determined to be A_2=-0.237±0.056 and A_4=0.39±0.062. The measured correlation establishes the spin sequence to be 2-2-0, with a quadrupoledipole mixing ratio δ of -(4^+3_-2) for the 0.80 MeV gamma-ray. The results of the angular correlation work together with the allowed nature (log ft=5.7) of the electron capture decay to the 1.88 MeV level fix the spin and parity of this level to be 2+.
