The ability of the field ion microscope to routinely visualize                  individual atoms on a crystal will be utilized to quantitatively                characterize different aspects of metal clusters on metal                       surfaces:                                                                                                                                                            a. Atomic Interactions and Cohesion of Clusters                            From measurements of the equilibrium pair distribution function,                the interactions between two atoms will be determined on smooth                 planes of bcc as well as fcc metals.  Experiments on different                  adatoms and on different surfaces will explore chemical and                     structural effects on the interactions.                                                                                                                              b.  Cluster Formation and Mobility                                         The growth and structural transformations of metal clusters will                be examined on densely packed planes of fcc and bcc metals.                     Diffusion of clusters will be studied to establish uder what                    conditions motion of the cluster as a whole dominates its                       mobility.                                                                                                                                                            c.  Chemical Reactivity of Clusters                                        If time permits, the ability of metal clusters, characterized by                field ion microscopy, to catalyze dissociative chemisorption will               be tested on smooth planes on which chemisorption is otherwise                  slow.//
