Application of the generalized-exchange local-spin-density-functional theory: Negative ions.

The generalized-exchange local-spin-density-functional theory with self-interaction correction has been used to calculate negative ions. The effect of the Fermi hole in the negative ions is discussed. The results are compared with experiment, Hartree-Fock, and other theoretical methods. It is shown that relaxation and correlation effects are very important for the negative ions.
