摘要利用灵敏的辐射探测共振电离光谱（RADRIS）技术鉴定了中性铌（No，Z= 102）的光学跃迁。延迟电离激光时的残余信号表明了强缓冲气体引起的光填充能级去激发的影响。随后对化学同系物镱（Yb，Z= 70）的研究，使得对这一过程中涉及的原子水平的详细研究成为可能，从而导致了速率方程模型的发展。这为表征共振电离光谱（RIS）方案铺平了道路，用于研究铌和其他原子性质目前未知的地方。图形抽象
AbstractUsing the sensitive Radiation Detected Resonance Ionization Spectroscopy (RADRIS) technique an optical transition in neutral nobelium (No,Z= 102) was identified. A remnant signal when delaying the ionizing laser indicated the influence of a strong buffer gas induced de-excitation of the optically populated level. A subsequent investigation of the chemical homologue, ytterbium (Yb,Z= 70), enabled a detailed study of the atomic levels involved in this process, leading to the development of a rate equation model. This paves the way for characterizing resonance ionization spectroscopy (RIS) schemes used in the study of nobelium and beyond, where atomic properties are currently unknown.Graphical abstract
