Measurements are reported of surface plasmon energy and dispersion carried out by electron energy loss spectroscopy on Ag(110) along both high-symmetry crystallographic directions. For small q_∥ the data show a linear and positive dispersion with a strong azimuthal dependence that is twice as large along the 〈001〉 direction as along 〈11{}0〉.
