M. A. Van Hove Lawrence Berkeley National Laboratory, Berkeley, and University of California, Davis Three distinct topics are presented, all of which exploit theory applied to synchrotron radiation experiments. First, theoretical studies of photoelectron diffraction from "fixed-in-space" molecules (CO and N2) are presented: these show high sensitivity to intra-molecular resonances, and also explore the issue of quantum coherence vs. incoherence in photoemission. Next, the principles of Resonant X-ray Fluorescence Holography are modeled to analyze the capability of this method to image local atomic environments around selected chemical elements. Third, calculations are presented for quantum-well states confined in Cu thin films: issues pertaining to "wave function engineering" will be discussed. Back to SSRL Users' Meeting Program |
