This research employs MEIS (medium energy ion scattering)                       combined with channeling and blocking to describe the three-                    dimensional geometric surface structure and vibrational                         characteristics of metal and semiconductor surfaces.  Computer                  simulation of scattering from the examined surfaces assists in                  the structure analysis.  Initial emphasis in the program is on                  iron, aluminum, copper, silicon and germanium.  This research                   provides experimental data needed for development of theories of                surface structure.
