The interaction between rare gas clusters and intense XUV light pulses provided by FEL reveals an complex and ultrafast dynamics. Size selected measurements are able to dinsentangle the dynamics for clusters having different cluster sizes or interacting with different local intensities within the FEL focus (1). Electron spectra are extremely well suited to investigate properties of the nanoplasma building up within the cluster, as well as the change of the binding energies of the core level during interaction. In addition to the ion spectra already investigated, they are signatures for the underlying interaction process. Up to now averaged electron spectra are available (2), size selected measurements are strongly desirable. In this contribution results from a beamtime at FLASH are presented, where xenon clusters were irradiated by FEL pulses with a wavelength of 13.5 nm.
