Abstrakt:
The nuclear shell model predicts that the next doubly magic shell-closure beyond 208Pb
is at a proton number Z = 114, 120, or 126 and at a neutron number N = 172 or 184.
The outstanding aim of experimental investigations is the exploration of this region of
spherical `Super-Heavy Elements' (SHEs). The measured decay data reveal that for the
heaviest elements, the dominant decay mode is Q emission, not fission. Decay properties
as well as reaction cross-sections are compared with results of theoretical investigations.
Finally, plans are presented for the further development of the experimental set-up and
the application of new techniques. At a higher sensitivity, the exploration of the region
of spherical SHEs now becomes feasible, more than thirty years after its prediction.
