Surface yield measurements with single-alignment high-energy ion scattering, at normal incidence, are used to show that the Cu(110)-(2[times]3)-N surface is reconstructed according to an additional-row model, where the first-layer density of Cu atoms is increased to 4/3 monolayers. A surface-reconstruction model involving missing rows can be excluded. We also find that 2/3 of the second- and third-layer atoms are displaced laterally, from their bulklike positions, by 0.30 and 0.07 A, respectively. Off-normal-incidence measurements indicate additional vertical atomic displacements in the second and third layers.
