In ballistic open quantum systems one often observes that the resonances in the complex-energy plane form a clear chain structure. Taking the open 3-disk system as a paradigmatic model system, we investigate how this chain structure is reflected in the scattering states and how it is connected to the underlying classical dynamics. Furthermore we present a simple open quantum graph model consisting of two edges that shows surprisingly similar behaviour in its resonance structure and scattering states.
