The reactions 3H(3H,2n)4He and 3He(3He,2p)4He are investigated within a fully microscopic cluster model featuring a three-cluster exit channel. A hyperspherical harmonics basis is used to describe the three-cluster continuum. The resulting astrophysical S factor of both reactions is in good agreement with experimental data. Analysis of the low-energy scattering parameters reveals no evidence for a hidden resonance state that would increase the cross section of the reactions, and would help to resolve the solar neutrino problem.
