Abstract
The calculational methods in atomic structure are currently capable of providing the level of accuracy close to that of the most precise experiments. The multiconfiguration Hartee-Fock method is applied to calculation of the 4d 4f energy difference in Li I using two ab initio approximations, namely, the active space method and the corepolarization approximation. The latter method is shown to agree with the most accurate available experimental data.Citation
