ROOTHAAN-HARTREE-FOCK WAVE-FUNCTIONS FOR CATIONS AND ANIONS IN SLATER-TYPE BASIS-SETS WITH DOUBLY EVEN TEMPERED EXPONENTS

Roothaan-Hartree-Fock wave functions in Slater-type basis sets are rep orted for the cations Li+-Cs+ and anions H--I- using the double even t empering (DET) method of selecting orbital exponents. The DET total en emies do not differ from the corresponding numerical Hartree-Fock valu es by more than 0.2 millihartrees for the cations and anions. The pres ent results together with the previous ones for neutral atoms [Theor C him Acta 88:273 (1994)] provide a compilation of DET wave functions of near Hartree-Fock quality for all the neutral and singly-charged atom s with the number of electrons N less than or equal to 54.
