摘要：

Sources of 78.4 h 89Zr were produced by the 89Y(p, n)89Zr reaction, and the decay properties were studied with Ge(Li) detectors. The energies of previously reported γ-ray transitions were measured as Eγ = 909.1±0.1, 1620.6±0.7 and 1713.0±0.6 keV. Two new transitions of Eγ = 1656.9±0.7 and 1744.4±0.7 keV were also observed, the latter being assigned as a ground state transition from the 5 2- state. The absence of any observed cascade feeding of this state leads to log ft = 8.3 for this unique first-forbidden transition. © 1968.
