The β- decaying γ scheme of the neutron-rich nuclide 208Hg has been determined for the first time.The 208 Hg was produced in multi-nucleon transfer reaction taking place in the bombardment of 18O-beam on natural lead target,and the Hg-element products were sepaated with a gas-thermochromatography technique.The γ-ray single and γ-γ coincident spectra were measured.A partial 208 Hg γ scheme was proposed.Twenty-six γ rays were assigned to follow the β- decay of 208Hg.At the same time,a new level structure of the daughter nucleus 208 T1 was constructed,in which three new levels at 1.725MeV.1.652MeV,and 1.362MeV were affirmed.The experimental 208Tl level structure was compared with a shell-model calculation. 相似文献
