Cover:
The front cover shows in summary the nuclear decay chains measured in the first element
114 experiment at the GSI Helmholtzzentrum für Schwerionenforschung. This is the
heaviest element ever observed at the GSI. A 48Ca beam from the UNILAC impinging on
244Pu targets was used for its synthesis. The isotopes 288114 and 289114 were separated
with the highly efficient gas-filled recoil separator TASCA (TransActinide Separator and
Chemistry Apparatus), and statistically highly significant data were obtained. A newly
developed focal plane detector allowed for the safe identification of the nuclear decays of
the element 114 isotopes and their daughter nuclides. A so far unknown α-decay branch
in 281Ds as well as the new isotope 277Hs, which exhibits an interestingly short
spontaneous fission half-life, were discovered in the course of this experiment, which was
performed in the summer of 2009. Relatively high cross sections were measured for the
element 114 isotopes, which pave the way for further experiments with this element.
The background displays in an artist's view the periodic table. It does not only reflect
chemist's main 'road map' but it also emphasizes the position of element 114 and alludes
to the first element 114 chemistry experiment performed at GSI in the fall of 2009.
Element 112, which was discovered several years ago by the SHIP group at GSI, is also
highlighted. Most recently, the International Union of Pure and Applied Chemistry
accepted the name Copernicium and the chemical symbol Cn for element 112, as
proposed by the discovery team.
