论文摘要

对单电离碳谱的所有可用实验数据均已严格分析。所有已发表研究的测量不确定性都已重新评估。观察数据的范围包括带有光栅和傅立叶变换光谱仪,实验室光吸收光谱以及行星烟囱的发射光谱记录的弧,火花,无电排放和空心阴极灯的实验室发射光谱。此汇编中包含的观察到的光谱线的总数为597。这些线参与了972个过渡。从此确定的过渡列表中,我们得出了一组414个能级,这些能量水平是使用最小二乘拟合程序进行了优化的。标识是通过COWAN代码的参数计算支持的。现有的批判性评估过渡概率表已通过我们的新计算数据扩展。电离能量是从新近优化的能级以提高精度得出的。同位素偏移和超细结构的数据也已经编译。

All available experimental data on the spectrum of singly ionized carbon have been critically analyzed. Measurement uncertainties of all published studies have been re-assessed. The scope of observational data includes laboratory emission spectra of arcs, sparks, electrodeless discharges, and hollow cathode lamps recorded with grating and Fourier transform spectrometers, laboratory photoabsorption spectra, and emission spectra of planetary nebulae. The total number of observed spectral lines included in this compilation is 597. These lines participate in 972 transitions. From this list of identified transitions, we have derived a set of 414 energy levels, which are optimized using a least-squares fitting procedure. The identifications are supported by parametric calculations with Cowan's codes. The existing tables of critically evaluated transition probabilities have been extended with our newly calculated data. The ionization energy has been derived from the newly optimized energy levels with improved precision. Data on isotope shifts and hyperfine structure have also been compiled.
