Its small mass and strong interaction with the host electrons and nuclei are responsible for many anomalous and interesting solid state effects. In addition, hydrogen in metals gives rise to a number of technological problems such as hydrogen embrittlement, hydrogen storage, radiation hardening, first wall problems associated with nuclear fusion reactors, and degradation of the fuel cladding in fission reactors. Both the fundamental effects and applied problems have stimulated a great deal of inter est in the study of metal hydrogen systems in recent years. This is evident from a growing list of publications as well as several international conferences held in this field during the past decade. It is clear that a fundamental understanding of these problems re quires a firm knowledge of the basic interactions between hydrogen, host metal atoms, intrinsic lattice defects and electrons. This understanding is made particularly difficult by hyrogen's small mass and by the large lattice distortions that accompany the hydrogenation process. The purpose of the "International Symposium on the Electronic Structure and Properties of Hydrogen in Metals" held in Richmond, Virginia, March 4-6, 1982 was to increase our fundamental under standing of hydrogen in metals. Such knowledge is essential in solving technologically important questions. The symposium con sisted of twenty-two invited papers and seventy-two contributed poster presentations and attracted nearly 150 participants from thirteen countries. The proceedings of this symposium constitute this book.

Book excerpt: Cesium, hydrogen and oxygen adsorption on beryllium clusters are studied using restricted Hartree-Fock (RHF) calculations and ab initio relativistic effective core potentials. The clusters are taken as cylindrical plugs from beryllium wafers. Cs( - ), H( - ) and 0-to-substrate internuclear distances are optimized. For each system numerous low-lying electronic states are investigated and Mulliken electron populations analyzed. RHF calculations show that Be19, with three layers of atoms, is too small to adequately model the Be surface, while Be33, a five-layered system, and Be45, a seven-layered system, are more accurate representations of the bulk metal. The emitted electron is clearly seen as vacating a molecular orbital which is localized in the surface layer of the cluster, thereby giving further credence to the model. RHF calculations are completed for Pbl and Bil semiconductor clusters. Blue shifts in optical spectra and geometry changes are shown to be due to quantum size effects. Scanning tunneling microscopy is used to investigate the nature of colloidal particles in the 15 nm diameter size range. Images show a near monodispersion of small gold clusters. A model of the STM tip as a polyatomic crystalline surface is shown to correctly explain observations of anomalous long range order.
