Highly energetic irradiation of atoms, molecules and clusters can lead to single or multiple ionizations depending on the photon energy. The resulting ionized system can then undergo a multitude of relaxation processes of which the electronic decay reactions are in our focus. In order to determine the decay pathways it is of crucial importance to obtain a good characterization of the intermediate ionized state according to ionization probabilities, lifetimes and electronic structure in terms of participating orbitals and configurations.|
