“…While different theories do not agree on the precise location of this area, they all agree on its existence. Shell effects also play a major role in the structure of deformed SHE around Z=108 N=162 [1]. Deformation not only brings an increase in stability for these SHE, but also for nuclei situated in the vicinity of the nucleus 254 No (Z=102, N=152).…”

“…Fluoride complexation was also studied by anion-exchange chromatography at higher acid concentrations from 1.9 to 13.9 M HF solution [172] 2− -similar to the well known ZrF 6 2− and HfF 6 2− at lower [HF] -whereas Zr and Hf are presumably present in the forms of ZrF 7 3− and HfF 7 3− . The capabilities of AIDA were demonstrated in the first elution curve measurement of a superheavy element in liquid chromatography [138].…”

“…It was one key event, the conference at Lysekil in the year 1966 [5], which gave the starting signal for the rush into the new era of superheavy element science. In this year, seminal work by Myers and Swiatecki [6] and by Sobiczewski and coworkers [7] was published, and Meldner [8] presented his outstanding work at Lysekil. While early and more qualitative work of Wheeler [9] -who coined the term superheavy elementand Scharff-Goldhaber [10] made it conceivable that superheavy elements may exist around atomic number Z = 126, these new results now focused on the existence of an "island of stability" centered at Z = 114 and neutron number N = 184.…”

Summary. The chemistry of superheavy elements -or transactinides from their position in the Periodic Table -is summarized. After giving an overview over historical developments, nuclear aspects about synthesis of neutron-rich isotopes of these elements, produced in hot-fusion reactions, and their nuclear decay properties are briefly mentioned. Specific requirements to cope with the one-atom-at-a-time situation in automated chemical separations and recent developments in aqueous-phase and gas-phase chemistry are presented. Exciting, current developments, first applications, and future prospects of chemical separations behind physical recoil separators ("pre-separator") are discussed in detail. The status of our current knowledge about the chemistry of rutherfordium (Rf, element 104), dubnium (Db, element 105), seaborgium (Sg, element 106), bohrium (Bh, element 107), hassium (Hs, element 108), copernicium (Cn, element 112), and element 114 is discussed from an experimental point of view. Recent results are emphasized and compared with empirical extrapolations and with fully-relativistic theoretical calculations, especially also under the aspect of the architecture of the Periodic Table.

It is expected that the cross section for super-heavy nuclei production of Z > 118 is dropping into the region of tens of femto barns. This creates a serious limitation for the complete fusion technique that is used so far. Moreover, the available combinations of the neutron to proton ratio of stable projectiles and targets are quite limited and it can be difficult to reach the island of stability of super heavy elements using complete fusion reactions with stable projectiles. In this context, a new experimental investigation of mechanisms other than complete fusion of heavy nuclei and a novel experimental technique are invented for our search of super-and hyper-nuclei. This contribution is focused on that technique.
