For the first time, a clean metal surface reconstruction, viz. Pt(110)(2 x 1), was investigated using X-ray photo-electron diffraction. Comparison of the obtained experimental photo-electron diffraction azimuthal and polar curves with quasi-dynamic calculations reveals that the Pt(110)-(2 x 1) reconstruction is, as expected, of the “missing row model” type and, furthermore, presents a first layer contraction estimated to be around 30%. The result was compared with previous low-energy electron diffraction results.
