Fe Ⅰ跃迁频率的相对论修正和精细结构常数变化的研究

Relativistic corrections to transition frequencies of Fe I and search for variation of the fine structure constant

V. A. Dzuba, V. V. Flambaum

摘要:

用Dirac-Hartree-Fock方法和组态相互作用技术计算了Fe低能级的相对论能移。所得结果可用于研究类星体吸收谱精细结构常数的时空变化。到目前为止,在分析中使用的偏移值是最大的。这使得Fe成为纳入分析的良好候选者。

英文摘要:

Relativistic energy shifts of the low energy levels of Fe have been calculated using the Dirac-Hartree-Fock and configuration interaction techniques. The results are to be used in the search for the space-time variation of the fine structure constant in quasar absorption spectra. The values of the shifts are the largest among those used in the analysis so far. This makes Fe a good candidate for the inclusion into the analysis.
