论文摘要
我们报告了中性和单动性扫描剂（SC I和SC II）的新实验性超细结构（HFS）常数。我们使用傅立叶变换光谱仪观察到该区域200-2500 nm（50,000-4000 cm $^{ - 1} $的SC-AR和SC-NE空心阴极放电的光谱。该测量结果显示了表1中给出的12个光谱中安装的1431个光谱线中的显着HFS模式。使用计算机封装XGREMLIN拟合了这些光谱，以确定SC I的SC I和6个水平的磁性偶极性超精细相互作用常数（A），其中80个SC I水平没有先前的测量值。 HFS中的不确定性在1 $ \ times $ 10 $^{ - 4} $和5 $ \ times $ 10 $^{ - 4} $ cm $^{ - 1} $之间。
We report new experimental hyperfine structure (HFS) constants of neutral and singly ionized scandium (Sc I and Sc II). We observed spectra of Sc-Ar and Sc-Ne hollow cathode discharges in the region 200-2500 nm (50,000-4000 cm$^{-1}$) using Fourier transform spectrometers. The measurements show significant HFS patterns in 1431 spectral lines fitted in our 12 spectra given in Table 1. These were fitted using the computer package Xgremlin to determine the magnetic dipole hyperfine interaction constant (A) for 185 levels in Sc i and 6 levels in Sc II, of which 80 Sc I levels had no previous measurements. The uncertainty in the HFS A constant is between 1 $\times$ 10$^{-4}$ and 5 $\times$ 10$^{-4}$ cm$^{-1}$.
