A summary is given of a research program involving molecular beam spectroscopy of the alkali halides, the properties of metal surfaces, and a search for a possible charge difference between the proton and the electron.

THERMAL ENERGY MOLECULAR BEAMS HAVE BEEN USED TO STUDY CHEMICAL INTERACTIONS WITH METAL SURFACES. Chemisorption of simple molecules such as H2, O2, CH4, C2Hx and CO was investigated on single and polycrystalline surfaces of Pt, Ni, Co, and Ag. Kinetic parameters and reaction mechanisms were determined for model catalytic reactions including CO and C2Hx oxidation and methanation from H2/CO mixtures. Chemical reactions of NOx with CO and D2 on Pt(111) and other surfaces have been surveyed and the kinetics of NO and O2 chemisorption have been measured. The theory of adsorption/desorption kinetics is reviewed and certain deficiencies identified. (Author).
