We introduce a fully microscopic three-cluster model for light nuclei and discuss the dynamical equations for scattering. The three-cluster continuum is described by Hyperspherical Harmonics. The dynamical equations are solved by the Modified J-Matrix Method, which includes potential asymptotic information for fast convergence. We apply the methodology to the resonances of He-6 and Be-6 as well as to the S-factor of the reactions H-3(H-3, 2n)He-4 and He-3(He-3, 2p)He-4 in which the three-cluster description is used for the exit channel. The results are in good agreement with the experimental data.
