  We have studied the three-particle decay of 12C, 9Be and 6Be resonances.
These nuclei have been described as three-body systems by means of the complex
scaled hyperspherical adiabatic expansion method. The short-distance part of
the wave-function is responsible for the energies whereas the information
related to the observable decay properties is contained at large distances,
which must be computed accurately. As an illustration we show the results for
the angular distribution of 9Be and 6Be resonances.
