Effects of Core-valence and Core-core Correlation On the Line-strength of the Resonance Lines In Li-i and Na-i

Brage, Tomas LU ; Fischer, C. F and Jonsson, P (1994) In Physical Review A (Atomic, Molecular and Optical Physics) 49(3). p.2181-2184
Abstract
The resonance lines in Li I and Na I both exhibit a puzzling discrepancy between experiment and accurate ab initio calculations. Only results from a semiempirical method, that in principal neglects core-core correlation, agree with the experiments. The agreement with a multiconfiguration Hartree-Fock calculation, including only core-valence correlation, shows that this might be fortuitous. A method for including some core-core correlation is designed and gives results in excellent agreement with other accurate ab initio methods.
