Abstract: | The γ-ray decay spectrum of 82 s 59Cu produced by the 58Ni(p, γ) 59Cu reaction has been studied with a 40 cm3 Ge(Li) detector. The number of γ-rays now known for this decay has more than doubled. Additional direct β+ branches to the 1679.7(), 2414.8() and 2681 keV states of 59Ni have been identified with log ft values of 5.5, 5.5 and 6.0, respectively. A major change is the reassignment of the 1340.4 keV γ-ray to a 1679.7 → 339.3 keV transition. A limit of log is given for the direct feeding of the 1337() keV state, together with limits for direct population of other energetically available states. The new weak γ-ray branches found for the 878.0, 1301.5 and 1679.7 keV levels are in excellent agreement with the recent theoretical calculations of Glaudemans et al. |
