Angle resolved photoelectron spectra of small copper clusters — •Lukas Weise and Bernd v. Issendorff — Physikalisches Institut der Albert-Ludwigs-Universität Freiburg
Angle resolved spectra are important tests for the theoretical description of clusters since they carry more information than the energy spectra alone. The anisotropy of photoelectron spectra for example depends on the angular momentum state.
The cluster anions are produced in a magnetron sputter source and enter a time-of-flight spectrometer for mass measurement and selection. Afterwards electrons are detached by linear polarized laser light and projected onto a MCP detector in a velocity map imaging setup.
Here the results for small copper cluster are presented. Although copper clusters have been studied intensively, there are still undiscovered features of their photoelectron spectra. For example Cu5− shows a strong vibrational structure.
