Abstract
We report the first time-resolved studies of image-potential states on Ag(100). Femtosecond ultraviolet-pump and visible-probe techniques are combined with two-photon photoemission spectroscopu to measure transient photoemission spectra with femtosecond resolution. The lifetime of the image-potential state on Ag(100) is observed to be several tens of femtoseconds.
