摘要：

The γ-transitions in 60Ni following the decay of 60Cu have been investigated using a Ge(Li)NaI(Tl) coincidence-anticoincedence spectrometer. More than 20 previously unreported γ-transitions were observed, and six additional levels at 4007.8, 4318.8, 4760.7, 4843, (4848) and (5046) keV were found to be directly populated. A new 120.5+-0.3 keV branch (3.5%) between the 31+ (2626.2 keV) and the 41+ (2505.7 keV) states has been identified; it accounts for the major part of the M1 decay of the 31+ state. The branching of the 3124.1 keV 23+ state to the 01+ ground state and to the 2284.9 keV 02+ state yields B(E2: 23+ → 02+)/B(E2: 23+ → 01+) = 68+-7. On the basis of available evidence, we tentatively assign Jπ = 2+ to the 3269.4 and 3393.5 keV levels. © 1969.
