Phonon dispersion curves for the p(3 x 1)O-(110)Ag surface were measured along [1¯10}-type directions by means of inelastic He-atom scattering. A comparison with lattice dynamics calculations, assuming various arrangements of the surface Ag atoms, strongly supported a missing-row type of reconstruction model.
