Abstract：
The radioactive nuclide ¹⁸⁶Hf has been produced via multinucleon transfer reaction by 60MeV/u ¹⁸O 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 γ-ray from its daughter ¹⁸⁶Ta. The half-life of ¹⁸⁶Hf was determined to be (2.6±1.2) min.
