Abstract
The current state of the spectroscopy of image states by two-photon ph otoemission is reviewed. The high resolution permits the detection of several members of the Rydberg series and the determination of the int rinsic linewidth of these states. Recent results for metal overlayers show that the concept of the local work function can be applied and th at two-photon photoemission is a sensitive probe for the potential at the surface.
