|Title:||Large-scale MCHF Calculation of the Li I 4d-4f Energy Separation|
|Published:||November 01, 2007|
|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 Hartree-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 core-polarization approximation. The latter method is shown to agree with the most accurate available experimental data.|
