Chemical investigation of hassium (element 108)
TLDR
Evidence that the chemical properties of hassium and its lighter homologue osmium are similar is provided, thus confirming that hassio exhibits properties as expected from its position in group 8 of the periodic table.
48Ca+249Bk fusion reaction leading to element Z = 117: long-lived α-decaying 270Db and discovery of 266Lr.
TLDR
The superheavy element with atomic number Z=117 was produced as an evaporation residue in the (48)Ca+(249)Bk fusion reaction at the gas-filled recoil separator TASCA at GSI Darmstadt, Germany and a hitherto unknown α-decay branch in (270)Db was observed, which populated the new isotope (266)Lr.
Synthesis and detection of a seaborgium carbonyl complex
TLDR
A gas-phase carbonylation technique previously tested on short-lived molybdenum and tungsten isotopes was applied to the preparation of a carbonyl complex of seaborgium, the 106th element, and it was concluded that hexacarbonyl Sg(CO)6 was the most likely structural formula.
Spectroscopy of element 115 decay chains.
TLDR
For the first time, precise spectroscopy allows the derivation of excitation schemes of isotopes along the decay chains starting with elements Z>112.
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
Mechanisms Suppressing Superheavy Element Yields in Cold Fusion Reactions.
TLDR
The energy dependence of P_{CN} indicates that cold fusion reactions (involving ^{208}Pb) are not driven by a diffusion process, and that superheavy elements formed in fusion reactions which are hindered by fast nonequilibrium processes are formed.
Atom-at-a-time laser resonance ionization spectroscopy of nobelium
Optical spectroscopy of a primordial isotope has traditionally formed the basis for understanding the atomic structure of an element. Such studies have been conducted for most elements and
Superheavy element flerovium (element 114) is a volatile metal.
TLDR
A gas-solid chromatography study of the adsorption of Fl on a Au surface points to the formation of a metal-metal bond of Fl with Au, the least reactive element in the group, but still a metal.
Chemical characterization of bohrium (element 107)
TLDR
The chemical separation and characterization of six atoms of element 107 (bohrium, Bh), in the form of its oxychloride, is reported, finding that this compound is less volatile than the oxychlorides of the lighter elements of group VII, thus confirming relativistic calculations that predict the behaviour of bohrium to coincide with that expected on the basis of its position in the periodic table.
