Abstract
The reactions H-3(H-3,2n)He-4 and He-3(He-3,2p)He-4 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.
