Study of the Radiations Emitted in the Decay ofNi65

Radiations emitted in the decay of ${\mathrm{Ni}}^{65}$ have been studied using scintillation spectrometry and absolute beta counting. The half-life of this nuclide has been measured to be 2.553±0.008 h. A decay scheme is presented which contains some weak transitions observed to depopulate the higher energy states. Intensities are presented for these transitions and upper limits are placed on intensities of previously reported transitions which were not observed in this work.
