Abstract Theγ-rays from60Co have been studied with a 30 cm3 Ge(Li) detector. Gamma rays of energies 826.4 and 2,158.9 keV which are expected on the basis of the60Co decay scheme were sought but not observed. Their intensities are 〈0.02% and 〈0.002%, respectively, of the60Co disintegrations. Any direct feeding from the (5+)60Co ground state to the (2+) 2,159 keV level is 〈0.022%, yielding a logft〉12.3 for the 664 keV second-forbidden uniqueβ-transition. Radioactivity60Co; measuredE γ,I γ.60Ni deduced levels, logft. Ge(Li) detector.
