Abstract：
60MeV /u ¹⁸O ion beam delivered by the Heavy Ion Research Facility in Lanzhou (HIRFL) bombarded the natural tungsten targets. The ¹⁸⁶Hf was produced by multinucleon transfer reacions. The hafnium fraction was separated radiochemically from the mixture of tungsten and the reaction products. The γ activity was measured with a HPGe detector. The growth and decay of ¹⁸⁶)Ta γ-rays has been observed, which indicates the (186)Hf as a parent of ¹⁸⁶Ta were produced. The half-life of ¹⁸⁶Hf has been determined to be (2.6±1.2)min.
