Electron scattering and electromagnetic response properties of metal clusters

摘要

The response of metal clusters to inelastic electron impact and to external electromagnetic radiation is discussed. The delocalized valence electrons play a decisive role in determining the response properties. First, a description and interpretation of an inelastic electron scattering experiment are given, and a connection to electromagnetic response studies is pointed out. Secondly, a summary of a theoretical analytical description of the response properties of metal clusters is presented. Finally, the effect of non-sphericity on the electronic properties of clusters is analyzed.
