Abstract: Self-consistent-field (SCF) method using signle electron wave functions expanded in terms of Gaussian functions is reported for atoms in two dimensions. The energy expressions are derived for closed-shell and open-shell configurations comprising, s, p, and d electrons and Hartree-Fock-Roothaan two-dimensions equation for closed-shell atoms. Finally, main results of SCF numerical computations are given and discussed.

Key words: tow-dimensions atom, gaussian function expansion, SCF method
