Electronic structure of Li and F calculated directly in momentum space

  • Laurent De Windt

A self-consistent field method is applied to compute directly in momentum space the electronic structures of the bound anions Li and F at the Hartree-Fock level. The convergence towards the Hartree-Fock limit, starting from STO-3G, 3–21G, 3–21+G and 6–311+G AO's, is stable and monotonous. Substantial improvement in the quality of the anion orbitals is noted already after one iteration. Particularly interesting is the efficiency with which the method modifies and improves the shape of the trial functions.

Key words
