Book Description
Two techniques which have made important contributions to the understanding of surface phenomena are high resolution electron energy loss spectroscopy (EELS) and photoelectron diffraction (PD). EELS is capable of directly measuring the vibrational modes of clean and adsorbate covered metal surfaces. In this work, the design, construction, and performance of a new EELS spectrometer are described. These results are discussed in terms of possible structures of the O-Cu(001) system. Recommendations for improvements in this EELS spectrometer and guidelines for future spectrometers are given. PD experiments provide accurate quantitative information about the geometry of atoms and molecules adsorbed on metal surfaces. The technique has advantages when used to study disordered overlayers, molecular overlayers, multiple site systems, and adsorbates which are weak electron scatterers. Four experiments were carried out which exploit these advantages.

Book Description
The objective of this research program is to utilize high resolution electron energy loss spectroscopy and other spectroscopic tools to investigate chemical and physical properties of surfaces and of gas-surface interactions. Our experiments address issues pertaining to bond lengths and site symmetry of chemisorbed atoms and molecules at metal surfaces, binding energies and vibrational frequencies associated with the atomic and molecular bonds, and with the driving mechanisms responsible for structural transformations which occur at surfaces as a result of chemisorption or other perturbations such as temperature change. Our work also addresses possible improvements in experimental techniques and data analysis which offer expanded applications. Research accomplishments of the program include a significant advancement in instrumentation, the first measurements of shear horizontal vibrational modes at crystal surfaces, the first detection of projected bulk phonon modes by surface electron scattering and elucidation of novel properties associated with hydrogen interaction at Niobium surfaces. Keywords: Surface chemistry, Structure and electronic properties of surfaces, Electron scattering, Physical chemistry, Shear properties, Scattering. (jg).
