In electron energy loss spectroscopy ( EELS) a material is exposed to a beam of electrons with a known, narrow range of kinetic energies. Some of the electrons will undergo inelastic scattering, which means that they lose ... Nettet9. des. 2003 · Accordingly, the technique of optical simulation is employed in the analysis of LEED patterns obtained from complicated surface structures. The experimental method is described and applied to the determination of the arrangement of atoms responsible for several characteristic LEED patterns: Au (100) 5×10, Cu (100) + O 2, and W (100) + H 2. jeff zwiers building academic language
