A corrugated and stable ground state is found for the two-dimensional electron gas in both the normal paramagnetic and the fully polarized phases. The self-consistent Hartree-Fock method is used with a modulated set of trial wave functions within the deformable jellium model. The results for high metallic densities reproduce the usual noncorrugated ferromagnetic electron-gas behavior. A transition to a paramagnetic corrugated state for values of {ital r}{sub {ital s}}{approx}6.5 is predicted. At lower densities {ital r}{sub {ital s}}{approx}30, a second transition to a corrugated ferromagnetic phase is suggested.
