Lifetimes of image-potential states on the clean and hydrogen-covered Ni (111) surface
Lifetimes of image-potential states on the clean and hydrogen-covered Ni (111) surface
We have investigated the population dynamics of image-potential states on the clean and hydrogen-covered Ni(lll) surface using time-resolved two photon photoemission spectroscopy. On clean Ni(lll) a lifetime of 7 +/-3 fs for the n = 1 state is obtained. The increasing lifetime when the surface is sa...

We have investigated the population dynamics of image-potential states on the clean and hydrogen-covered Ni(lll) surface using time-resolved two photon photoemission spectroscopy. On clean Ni(lll) a lifetime of 7 +/-3 fs for the n = 1 state is obtained. The increasing lifetime when the surface is saturated with hydrogen is assigned to changes in the occupied valence electronic structure. (C) 2001 Elsevier Science B.V; All rights reserved. |
