The technique of ion backscattering and channeling provides valuable information
about the structure of solid surfaces, both clean and as modified by adsorbed atoms. Analysis
of the backscattering data is based on the concepts of shadowing and blocking. Because the
theory of Rutherford scattering is well understood, it is possible, using comparisons between
experiment and computer simulations for model structures, to extract information about the
geometry and dynamics of atoms on solid surfaces. Studies of the structure of clean W(110)
and Nb(110) surfaces, and the modification of these surfaces with H adsorption/absorption will
be presented. Ion scattering also provides structural information about solid-solid interfaces.
Results for Pd deposited on Al(111), and for Ni on W(110) will be discussed.
