论文摘要
通过该地区的傅立叶变换光谱仪测量的钴光谱进行了单电离钴(CO II)的超细结构常数分析$ 3000-63000 $ cm $^{ - 1} $($ 333333-159 $ nm)。适合$ 700 $的光谱线,导致估计$ 292 $磁性偶极性超精美相互作用$ a $常数,值在$ -32.5 $ MK和$ 59.5 $ MK($ 1 $ MK $ = 0.001 $ CM $ CM $^{ - 1} $)之间。 $ 255 $的不确定性在$ \ pm0.4 $ mk和$ \ pm3.0 $ mk之间,其余$ 37 $范围为$ \ pm7 $ mk。电动四极杆超精细相互作用$ b $常数的估计仅为$ 1 $ $。现在已知$ a $值的CO II水平的数量已经增加了十倍,从而改善并使CO II在天文学化学丰度分析中更广泛,更可靠,更准确地应用。
Analysis of hyperfine structure constants of singly ionised cobalt (Co II) were performed on cobalt spectra measured by Fourier transform spectrometers in the region $3000-63000$ cm$^{-1}$ ($3333-159$ nm). Fits to over $700$ spectral lines led to measurements of $292$ magnetic dipole hyperfine interaction $A$ constants, with values between $-32.5$ mK and $59.5$ mK ($1$ mK $=0.001$ cm$^{-1}$). Uncertainties of $255$ A constants were between $\pm0.4$ mK and $\pm3.0$ mK, the remaining $37$ ranged up to $\pm7$ mK. The electric quadrupole hyperfine interaction $B$ constant could be estimated for only $1$ energy level. The number of Co II levels with known $A$ values has now increased tenfold, improving and enabling the wider, more reliable and accurate application of Co II in astronomical chemical abundance analyses.
