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.

超重元素的激光共振色谱。

光谱学是积累有关原子及其结构的基础知识的历史之路。基于荧光和共振电离光谱的以前的工作使得能够识别直至元素102（bel）的光谱线。该研究领域面临的新挑战是较重元素的难熔性和产量下降。提出了一种离子迁移辅助激光光谱的新概念，以克服在超重元素区域中持续存在的原子结构研究的灵敏度极限。该概念提供了宽带级搜索和合成and以外的合成元素的高分辨率超精细光谱的功能。
