Description
We discuss the three-body decay mechanisms of many-body resonances. Sequential decays proceed via two-body configurations after emission of the third particle. In direct decay all three particles leave simultaneously their interaction regions. The intermediate paths within the interaction regions are not observables and only accessible through models. The momentum distributions carry, apart from polarization, all possible information about decay modes and resonance structure. We use complex-scaled hyperspherical adiabatic expansion method to describe the three-body systems. The cases we use as examples (12C, 9Be and 6Be) present their own intriguing problems and they are moreover requested for astrophysical applications. When possible we compare our computed energy distributions with the experimental ones.
