Superheavy element flerovium (element 114) is a volatile metal.
The electron shell structure of superheavy elements, i.e., elements with atomic number Z ≥ 104, is influenced by strong relativistic effects caused by the high Z. Early atomic calculations on element 112 (copernicium, Cn) and element 114 (flerovium, Fl) having closed and quasi-closed electron shell configurations of 6d(10)7s(2) and 6d(10)7s(2)7p1/2(2), respectively, predicted them to be noble-g...
متن کاملSuperheavy-element spectroscopy: Correlations along element 115 decay chains
Following a brief summary of the region of the heaviest atomic nuclei yet created in the laboratory, data on more than hundred α-decay chains associated with the production of element 115 are combined to investigate time and energy correlations along the observed decay chains. Several of these are analysed using a new method for statistical assessments of lifetimes in sets of decay chains.

متن کاملFission time measurements: a new probe into superheavy element stability.
Reaction mechanism analyses performed with a 4pi detector for the systems 208Pb + Ge, 238U + Ni and 238U + Ge, combined with analyses of the associated reaction time distributions, provide us with evidence for nuclei with Z=120 and 124 living longer than 10(-18) s and arising from highly excited compound nuclei. By contrast, the neutron deficient nuclei with Z=114 possibly formed in 208Pb + Ge ...
متن کامل244Pu-targets for production of element 114 at TASCA
In a series of recent experiments at TASCA, production and decay as well as chemical properties of element 114 have been investigated using the Pu(Ca,3/4n)-reaction leading to 114 [1,2]. Because the Pu target material is available only in very limited amounts, the target preparation technique should give high yields. Easy and complete recovery of the target material is another prerequisite [3]....
