镱原子超精细结构常数的计算

Calculation of hyperfine structure constants for ytterbium

S. G. Porsev, Yu. G. Rakhlina, M. G. Kozlov

摘要:

计算了$^{173}$ Yb低能级的能量和超精细结构常数A和B。后者被视为双电子原子。为了解释价-价相关性,使用组态相互作用方法。在多体微扰理论中考虑了价核相关性,该理论用于在价空间中构造有效的双电子算符。

英文摘要:

We calculate energies and hyperfine structure constants A and B for low-lying levels of $^{173}$Yb. The latter is treated as a two-electron atom. To account for valence-valence correlations the configuration interaction method is used. Valence-core correlations are accounted for within the many-body perturbation theory which is used to construct effective two-electron operators in the valence space.
