Gamma Rays fromGa66

Twenty-four gamma-rays up to 4.8-MeV energy in the decay of 9.5-h ${\mathrm{Ga}}^{66}$ have been measured to an accuracy of 1.5 keV with a lithium-drifted germanium detector, and are assigned to a level scheme in close agreement to that of Schwarzschild and Grodzins. Prominent gamma-rays, useful in Ge(Li) calibration are: 4.8059, 4.4616, 4.2950, 4.0862, 3.7915, 3.3812, 3.2294, 2.7524, and 2.4231 MeV. The four highest energy values are 0.7-2.3 keV lower than the values of Coté et al.
