以铁为例讨论了类硅离子的结构（谱Fe XIII）。3s23p3d3Foterm有三个精细的结构水平，它们的寿命非常不同，这使得早期的观测无法进行。与此同时，互补的实验技术已经允许追踪这些水平。理论也从近似技术发展到精确的从头计算，其结果对早期的一些铁十三谱线识别提出了质疑，并指导了对日冕光谱中正确谱线的搜索和识别。
The structure of Si-like ions is discussed for the example of iron (spectrum Fe XIII). The 3s23p3d3Foterm with its three fine structure levels of very different lifetimes has eluded the early observations. Meanwhile, complementary experimental techniques have permitted to track these levels. Theory has also evolved from approximate techniques to accurate ab initio calculations, the results of which cast doubt on some earlier Fe XIII line identifications and guide the search for and the identification of the correct lines in solar corona spectra.
