Femtosecond studies of image-potential dynamics in metals

The first time-resolved studies of image-potential states on Ag(100) are presented. Femtosecond ultraviolet-pump and visible-probe techniques are combined with two-photon photoemission spectroscopy to measure transient photoemission spectra with femtosecond resolution. The lifetime of the n = 1 imag...

Beschreibung
Zusammenfassung:	The first time-resolved studies of image-potential states on Ag(100) are presented. Femtosecond ultraviolet-pump and visible-probe techniques are combined with two-photon photoemission spectroscopy to measure transient photoemission spectra with femtosecond resolution. The lifetime of the n = 1 image-potential state on Ag(100) is observed to be several tens of femtoseconds. 15 ref.--AA
