Abstract:

This project has involved a quantitative theoretical interpretation of electron spectroscopic data with a view toward elucidating the chemical environment and electronic structure of atoms in the bulk and adsorbed on solid surfaces. We have most recently examined XPS, XAS, and AES data for the high temperature superconductors, and CEELS, AES, and NEXAFS data for chemisorbed carbon species on metals. Electronphoton stimulated desorption ESDPSD was also of interest. Here, an interpretation of spectroscopic data allowed for the first quantitative determination of a dissociative attachment cross-section on a surface and new knowledge about the trajectory of the desorbing atom.
