摘要
本文报道了新丰中子同位素^(208)Hg的合成、鉴别及半衰期测定。
The new neutron-rich isotope ^(208)Hg has been identified for the first time from the reaction products in fully-stopping thick ^(nat)Pb target bombarded by 30 MeV/u ^(12)C beam provided by the Heavy Ion Research Facility in Lanzhou. Assignment of the nuclide ^(208)Hg was based on the measurements of the deacy γ energy and halflife of its daughter ^(208)Tl, which was grown up with ^(208)Hg β^-deacy. The half-life of ^(208)Hg β^- deacy was determined to be 42_(12)^(+23) min. The average production cross Section of ^(208)Hg over the incident energy region from Coulomb barrier to 30 MeV/u is found to be 1.14±0.5 μb.
