Abstract
The half life of57Ni has been measured by Ge/Li/ γ-ray spectroscopy. The57Ni radionuclide was created by bremsstrahlung impinging a sample of elemental Ni. Time change of the activity of the 1377.6-keV γ-ray following decay of57Ni was analyzed to obtain a half life of 35.54±0.05 h for57Ni.
