摘要
We investigate a simple generalization of the local-spin-density exchange-correlation approximation of density-functional theory from single to multi-determinantal states. The method is explicitly spin independent and trivially preserves multiplet spin degeneracies. Tests on multiplet splittings in a variety of low-lying configurations of first-row atoms and ions are presented.
