High resolution inelastic electron scattering measurements and full multiple-scattering calculations for Ni(100) and Ag(100) surfaces are presented and used to characterize, for the first time, shear horizontal surface phonon modes. Implications of these new capabilities for studies of surface structure, reconstruction, thin film epitaxy, and for exploring selectron rules that govern inelastic electron scattering are discussed.
