Abstract

Image states on the surface of bare and adsorbate covered metals form simple, near-surface, bound electron systems. These systems provide useful model systems for understanding the electron- transfer dynamics between an adsorbate molecule and its underlying substrate. These states may be readily detected by two-photon photoemission, a technique ideally suited for high- resolution studies of excited surface states. Because of its relatively narrow linewidths, spectroscopy of the image states provides a useful method of detecting changes in surface and composition.
