新丰中子同位素:~(186)Hf

The radioactive nuclide 186Hf has been produced via multinucleon transfer reaction by 60 MeV / u 18 O ion irradiation of the natural tungsten. The radiochemical separation was performed to isolate the hafnium from tungsten and the complex mixture of the reaction products. The activity of the hafnium was measured using a HPGe detector The new neutron-rich isotope 186Hf has been identified for the first time by measuring the growth and decay of the 737.5keV - ray from its daughter 186Ta. The half-life of186H...
