摘要
The resonance X-ray scattering from the unmodified, clean Pt(1 1 1)surface is compared to theoretically predicted scattering Self-consistent real-space multiple-scattering approach is used to calculate the real and imaginary parts of the atomic platinum scattering factor. The experimentally observed near-edge fine structures of the surface scattering and fluorescence intensities are well reproduced by the calculations. In addition, more details are presented on our previous study [Phys. Rev. Lett. 83, 552 (1999)] of electrochemically formed oxide monolayer an the Pt(1 1 1) surface. (C) 2000 Elsevier Science B.V.
