Abstract：
The ²⁰⁸Hg has been produced in multi-nucleon transfer reactions induced by ¹⁸O ion beam on a thick,natural lead target.The irradiated lead pieces were put into agasthermochromatographic device, in which the Hg-element products were separated and collected.The 4πΔE _βγ-γ and γ-X(γ) coincidence as well as time-succesive γ-ray single spectrum measurements were performed. A partial γ scheme following ²⁰⁸Hg β ^－decay has been proposed for the first time, which has taken into account 21 γ-rays and two new energy levels at 1365 and 1727keV,respectively.
