论文摘要
在这项研究中,我们研究了43种原子thulium光谱线的超细结构。我们分析了从700 nm到2250 nm的波长范围内的傅立叶变换光谱,该光谱分别对应于14300 cm-1至4440 cm-1的波数范围。激发的thulium原子是在空心阴极灯中产生的。这项研究的结果是,已经通过实验确定了17个精细结构水平的磁偶极性超精细常数a,其中14个是第一次。文献中报道的剩余三个水平的磁偶极性超精细恒定值与我们的确定结果显着不同。
In this study, we investigated the hyperfine structure of 43 spectral lines of atomic thulium. We analyzed Fourier-transform spectra in the wavelength range from 700 nm to 2250 nm, which corresponds to the wavenumber range from 14300 cm-1 to 4440 cm-1, respectively. The excited thulium atoms were generated in a hollow-cathode lamp. As a result of this investigation, the magnetic-dipole hyperfine constant A of 17 fine structure levels have been determined experimentally, 14 of them for the first time. The magnetic-dipole hyperfine constant values of the three remaining levels, reported in the literature, differed significantly from the results of our determination.
