论文摘要
根据实验室光谱和原子数据计算的新测量，讨论了波长193-197Å的Fe VII发射线的识别。该区域对于从HINODE航天器上的EUV成像光谱仪（EIS）的太阳光谱进行研究至关重要，Hinode spacecraft在这些波长下具有峰值灵敏度。测量了十条线，这是由$ 3P^53d^3 $配置中的七个精细结构水平产生的。以前尚未报告两行，并导致$（a^2d）^3f_ {2,3} $级别的新实验能量。对于其余水平，获得了更新的实验能。新的原子模型用于计算两个密度诊断比的理论值$λ$ 196.21/$ 195.39和$λ$ 196.21/$ 196.21/$λ$ 196.06，密度源自Coronal Loop Potoppoints的EIS EIS光谱。
The identifications of Fe VII emission lines in the wavelength range 193-197 Å are discussed in the light of new measurements of laboratory spectra and atomic data calculations. This region is of importance to studies of solar spectra from the EUV Imaging Spectrometer (EIS) on board the Hinode spacecraft, which has its peak sensitivity at these wavelengths. Ten lines are measured, arising from seven fine structure levels in the $3p^53d^3$ configuration. Two lines have not previously been reported and lead to new experimental energies for the $(a^2D)^3F_{2,3}$ levels. Updated experimental energies are obtained for the remaining levels. The new atomic model is used to compute theoretical values for the two density diagnostic ratios $λ$196.21/$λ$195.39 and $λ$196.21/$λ$196.06, and densities are derived from EIS spectra of coronal loop footpoints.
