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 [Nature (2016) 538:495]. The new challenges faced in this research field are the refractory nature of the heavier elements and the decreasing production yields. In this contribution, a new concept of ion mobility-assisted laser spectroscopy will be presented, which will enable 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.
