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