Photoelectron Spectroscopy and Dynamics of Adsorbates on Clusters

摘要

A simple sputter source of thermal silicon carbide cluster anions has been developed and tested. Vibrationally resolved photoelectron spectra have been obtained for a number of anions of the form Si(sub n)C(sub m(-)), with n + m <- 8. Full interpretation of the spectra requires accurate calculation of the anion structure, carried out in collaboration with Gordon (ISU) and Burggraf (AFIT). The first fully analyzed spectra and calculations for asymmetric species (n < m) are complete; two three manuscripts describe this work. A laser ablation ion source has been designed to produce the important (but difficult to produce) n = m Si(sub n)C(sub m(-)) ions. Other new work systematically investigates the complex electronic structure of the nickel column metal oxides.
