Results and plans for nuclear spectroscopy of superheavy nuclei: the Lund perspective

A survey of nuclear structure results obtained along $\alpha$-decay chains stemming from isotopes of element 114, Fl, and element 115, Mc, is presented. Measures taken to ensure a reliable hand-over of nuclear spectroscopy output to nuclear structure theory are outlined. Possible links between decay chains starting from element 117, Ts, and element 115, Mc, are commented on. The experiments were conducted with the TASISpec set-up placed in the focal plane of the TASCA separator at the GSI Helmholtzzentrum für Schwerionenforschung GmbH in Darmstadt, Germany. Plans to improve the decay-spectroscopy set-up towards future superheavy endeavours are described.
