Status and perspectives
This article reviews the following topics which were discussed at the 375th Wilhelm and Else Heraeus-Seminar Workshop on the Atomic Properties of the Heaviest Elements held from September 25–27, 2006… Expand
Chemical investigation of hassium (element 108)
The periodic table provides a classification of the chemical properties of the elements. But for the heaviest elements, the transactinides, this role of the periodic table reaches its limits because… Expand
Chemical properties of element 106 (seaborgium)
The synthesis, via nuclear fusion reactions, of elements heavier than the actinides, allows one to probe the limits of the periodic table as a means of classifying the elements. In particular,… Expand
Chemical characterization of bohrium (element 107)
The arrangement of the chemical elements in the periodic table highlights resemblances in chemical properties, which reflect the elements’ electronic structure. For the heaviest elements, however,… Expand
Evidence for relativistic effects in the chemistry of element 104
Abstract On the basis of thermodynamic extrapolations, the first transactinide element 104 (Rf=rutherfordium 1 ) is expected to form volatile tetrachlorides of lower volatility than those of the… Expand
248Cm(22Ne,xn)27-xSg reaction and the decay properties of 265Sg reexamined
Recent studies of the hot fusion reaction 248 Cm( 26 Mg,xn) 274-x Hs have provided new nuclear decay data on 265,266 Sg and confirmed the existence of an isomeric state in 261 Rf. The results… Expand
On the decay properties of 269Hs and indications for the new nuclide 270Hs
Abstract.In bombardments of 248Cm with 143.7-146.8 MeV 26Mg ions the nuclides 269Hs and presumably 270Hs were produced. After chemical isolation, Hs atoms were identified by observing genetically… Expand
On the Stability and Volatility of Group 8 Tetroxides, MO4 (M = Ruthenium, Osmium, and Hassium (Z = 108))
Recently, an experiment to chemically characterize for the first time a compound of the transactinide element hassium (Hs, Z = 108) has been performed. On the basis of the assumption that Hs will b...
