2012, Atomic Data and Nuclear Data TablesCitation Excerpt :A previously reported half-life of ∼10 min [133] was evidently incorrect. In the 1961 paper “The nuclide 182Hf”, Hutchin and Lindner reported the first observation of 182Hf [138]. A hafnum oxide target was irradiated with thermal neutron at the Idaho Falls Materials Testing Reactor.

2004, Nuclear Instruments and Methods in Physics Research, Section B: Beam Interactions with Materials and AtomsCitation Excerpt :In recent years, many measurements have been performed, after the new detection method of MC-ICPMS (Multi Collector Inductively Coupled Plasma Mass Spectrometry, starting around 1995) made it possible to measure W isotopes with the desired precision [5]. However, the half-life of 182Hf was measured only in connection with its discovery in neutron irradiated Hf samples more than 40 years ago [1,6,7]. The accepted value of 9 ± 2 million years has the largest uncertainty among important chronometers.
