The static dielectric function and the spin susceptibility of the homogeneous electron gas are determined within the Hartree-Fock approximation by numerical solution of the corresponding vertex equation. The results show an antiferromagnetic (spin-density-wave) instability of the paramagnetic state at metallic densities. The quality of the so-called variational solution of the vertex equation is investigated in detail.
