Structure and dynamics of gas phase metal clusters — •Bernd von Issendorff — Physikalisches Institut, Universität Freiburg, Germany

One of the clearest examples of a quantum size effect is the electron shell structure of simple (and not so simple) metal clusters, which has been studied in detail since the beginning of cluster physics. Photoelectron spectroscopy on size-selected clusters turned out to be an ideal tool to monitor this special electronic structure. Angle resolved photoelectron spectroscopy is even able to yield information about the wavefunctions of the electrons, as well as on the dynamics of the photoemission process [1]. The recent years have seen a constant improvement of the experimental techniques as well as of the theoretical methods used to simulate the results, which yields a new quality of insight, as was for example demonstrated for complex systems like zinc clusters [2]. Additionally the rapid development of new light sources like high intensity synchrotrons, free electron lasers and high harmonic sources offers a huge potential for experiments on clusters. I will discuss a number of experiments which have been done recently or are under development.
