The lower energy y-rays of 72Ge from the decay of 14 h 7ZGa have been studied using a 2 m curved-crystal spectrometer. Mlxang ratios for the 601,630, 894 and 1051 keV transmons were determined from the 7-~' dtrectlonal correlations The E0 content of the 630 keV, 2 +'-> 2 + transition was found to be less than 2%. A spin of 3 for the 2065 keV level has been uniquely determined El RADIOACTIVITY 72Ga [from 7XGa(n,)')]; measured Ey, ~'(0). 7ZGe deduced 1 mlxmg ratios, spin Curved-crystal spectrometer and Ge(L0 detectors

Curved-crystal spectrometers have been utilized to determine the energies of 21 gamma rays following the decays of 46Sc(T4x = 83.8 d), 82Br(7"1 = 35.4 h), 99Mo(T~ = 66.6 h) and 11°Agm(Tl = 25.3 d). Seventeen of these gamma rays have energies in the range between 550 keV and 1121 keV and thus provide a number of calibration standards which supplement the earlier standards published by Raeslde and others.
