Helium is a prototypical model for complex decaying systems. While being the simplest system beyond Hydrogen it exhibits intriguing features due to the electron electron interaction that leads to multiple decay channels. We present studies on the driven and undriven one dimensional Zee configuration that provide insight into its (auto-)fragmentation with resolution of distinct channels. Furthermore we show the planar configuration with non-vanishing angular momentum, focusing on surprisingly stable states. This gives rise to a comparative study of the corresponding classical Helium model.
