Abstract ： The new neutron-rich isotope 186 Hf has been produced through a multinucleon transfer reaction by irradiation of natural tungsten targets with 60 MeV/u 18 O projectiles. The 186 Hf activities were separated radiochemically from the tungsten and reaction product mixture. The γ-ray singles spectra were measured with a high resolution HPGe detector. The new isotope 186Hf was identified based on the growth and decay of 737.5keV γ rays from the β- decay of its daughter 186 Ta. Its half-life has been determined to be 2.6 ± 1.2 min.
