Synchrotron radiation photoelectron diffraction (FED) from the Si(001)2×2-In surface was measured for the well resolved In 4d spin-orbit doublet (4d3/2 and 4d5/2) at photon energy of 100 eV. It is found that the two diffraction patterns originating from different core-level states are notably different from each other. A multiple scattering cluster method was applied to analyze both PED's. The optimized structures from the two patterns take essentially a similar parallel In-dimer model, but the radial matrix elments and phase shifts of the photoelectron continuums are different for the two components. We attribute this unexpected result to a spin-orbit coupling effect near the Cooper minima.
