The striped structure of the partially oxidized Cu(110) surface-has been studied using a novel technique, momentum-resolved electron stimulated desorption ion angular distribution (ESDIAD) Long O-...-Cu-O-.... strings oriented in the (001) direction and exhibiting attractive interactions with each other form periodically arranged stripes with widths in the nanometer range [D.. J. Coulman et at., Phys. Rev. Lett. 64, 1761 (1990); K. Kern et al., ibid. 67, 855 (1991)]. Two different oxygen sites were detected, leading to a twofold symmetrical four-beam O+ ESDIAD pattern-with 22 degrees tilting of the beams in the (1 (1) over bar 0) azimuth (A) direction and 8 degrees in the (001)azimuth (B)direction. The relative intensities of the four beams have been compared for a wide range of oxygen coverages leading to st model in which the A beams correspond to O+ ions desorbing from-the edges of the stripes and the B beams from the internal regions of the stripes. This model is confirmed by studying the effect of the coadsorption of Ar at 32 K on the oxidized structure-where the Ar is preferentially adsorbed on the edges of the stripes. The dynamical motion of the one-dimensional O-...-Cu-O-... oscillator chains situated at the edges of the stripes has been studied by momentum-resolved ESDIAD measurements over a broad range of temperatures (80-650 K).
