摘要

利用傅里叶变换光谱测定了铌原子高能级的超精细结构常数。结果得到了完整的前期研究，主要利用激光光谱[JQSRT(2020) 245, 106871, 106872, 106873]。本文共测定了144个能级的hf常数A，其中55个为首次报道。现在，对于几乎所有已知的原子Nb能级，超精细常数A都是可用的。此外，还发现了四个以前未知的能级。

Systematic investigations of the hyperfine structure constants of Niobium I levels. Part IV: New results derived from Fourier-transform spectra, including the discovery of four new levels

A determination of the hyperfine structure constants of high lying energy levels of the Niobium (Nb) atom was performed using Fourier-transform spectra. The results obtained complete previous investigations using mainly laser spectroscopy [JQSRT (2020) 245, 106871, 106872, 106873]. In the present work, the hf constants A of altogether 144 levels could be determined, among them 55 levels for which these constants are reported for the first time. Now for nearly all known energy levels of atomic Nb the hyperfine constants A are available. Further the discovery of four previously unknown energy levels is reported.
