We describe experiments on photoionisation of a free cluster jet with synchrotron radiation. Electron spectroscopy allows to map changes of the electronic structure upon condensation of monomers to clusters. Energy remaining in the cluster after photoionization can be released via emission of a secondary electron, which proceeds by an ultrafast energy transfer between neighbouring atoms or molecules within the cluster.
