We demonstrate that in order for hydrodynamic-model calculations to reproduce recent photoemission yield spectra the parameters must be chosen to ensure the existence of an extra surface collective mode below the plasma frequency. Hence, the agreement between these model calculations and the data establishes for the first time the existence of such modes on a smooth clean metal surface.
