  Optical spectroscopy constitutes the historical path to accumulate basic
knowledge on the atom and its structure. Former work based on fluorescence and
resonance ionization spectroscopy enabled identifying optical spectral lines up
to element 102, nobelium. The new challenges faced in this research field are
the refractory nature of the heavier elements and the decreasing production
yields. A new concept of ion-mobility-assisted laser spectroscopy is proposed
to overcome the sensitivity limits of atomic structure investigations
persisting in the region of the superheavy elements. The concept offers
capabilities of both broadband-level searches and high-resolution hyperfine
spectroscopy of synthetic elements beyond nobelium.
