Progress has included (1) construction and installation of an ultraviolet photoelectron spectrometer (UPS) with power supply and pumping system that has been added as an attachment to the SCIENTA ESCA-300 instrument, (2) modification of the high resolution electron energy loss spectrometer (HREELS) to produce a stable ultra high vacuum (UHV) environment for initial experiments with a Pd(311) single crystal, (3) construction of a separate high vacuum system for preparation of surface doped model catalysts by chemical vapor deposition and pretreatment of a Pd(100) single crystal in this system, (4) carried out detailed experiments of methane activation and oxidation on Pd(679) using a high pressure reaction cell contained in a third ultra high vacuum system, (5) completion of adsorption/desorption studies of H{sub 2}, CO, and O{sub 2} on Pd(679), (6) utilized angle-resolved XPS to probe the diffraction characteristics and structure of the Pd(100) surface, (7) determination of the electronic surface structure of Pd(100) using angle-resolved UPS, and (8) computational analysis of oxygen overlayers on the PD(100) surface. Each of these is discussed in further detail below.
