Photoionization of Xenon Clusters
- Conference date: 28-30 July 2005
- Location: Buenos Aires (Argentina)
High resolution photoelectron spectra of xenon clusters of about 100 atoms, measured with photon energies of 20 to 60 eV are reported. Peaks due to the clusters are observed at lower binding energies than the corresponding atomic lines and exhibit different behaviors. The peak associated with the Xe 5p1/2 state at higher binding energy is relatively unchanged with photon energy whereas the Xe 5p3/2 peak changes its shape with increasing photon energy. The change is attributed to differences in the escape depth of the electrons at different kinetic energies and the bulk and surface components of the cluster.
