A model of itinerant lattice electrons interacting with classical nuclei is studied. The electrons can interact between themselves via a Hubbard on-site term, It is shown that, in the ground state of the half-filled band, the nuclei form a periodic crystal. More precisely for a cubic lattice they fo
