Abstract High-resolution He atom inelastic-scattering experiments provide evidence for the shear horizontal surface phonons on the {ital in} {ital situ} cleaved NaCl(001) surface. The measurements were made in a sagittal plane along the [210] azimuth and beyond the first surface Brillouin zone. A slab calculation using the breathing shell model and a surface perturbation that fulfills invariance conditions is used to identify the polarizations of the observed surface phonons. {copyright} {ital 1996 The American Physical Society.}
