Deformed Hartree-Fock solutions for atoms. III. Convergent iterative process and results forO−−

Abstract

We present a systematic study of self-consistent symmetries (SCS) for the ten-electron atom ${\mathrm{O}}^{--}$ in an $s+p$ basis. The investigation of each SCS required a detailed study of the character of the iterative process. Convergency is ensured by a minimum-energy selection principle. Six deformed Hartree-Fock solutions for ${\mathrm{O}}^{--}$ have been obtained.
