A charge density wave mechanism was shown to explain the anomalous temperature-dependent diffraction peaks observed by high-resolution He scattering experiments accompanying the reconstruction of the clean W(001) surface. This model also accounts for the differences found in the electron and the He atom diffraction patterns.
