Surface structure determination of the (2x1)O-Cu(110) reconstruction by low-energy ion scattering
Using impact collision ion scattering it is shown that the reconstruction of the (2 x 1)O-Cu(110) surface is of the missing-row type where every other  row of copper atoms is missing. The oxygen atoms are located 0.08+/-0.15 Angstrom below the copper atoms of the remaining rows. The second layer copper atoms are shifted laterally 0.12+/-0.07 Angstrom away from the oxygen atoms in a pairing-row type reconstruction. The first layer is relaxed outward over 0.23+/-0.04 Angstrom compared to the ideal spacing, whereas the distance between the second and third layer remains unchanged. A critical comparison of the results with the data available in the literature shows that the position of copper and oxygen atoms can be determined with an accuracy of about 0.05 and 0.15 Angstrom, respectively.
