    "abstract": "The He3(He3,2p)He4 and H3(H3,2n)He4 reactions are studied in a microscopic\ncluster model. We search for resonances in the He3+He3 and He4+p+p channels\nusing methods that treat the two- and three-body resonance asymptotics\ncorrectly. Our results show that the existence of a low-energy resonance or\nvirtual state, which could influence the Be-7 and B-8 solar neutrino fluxes, is\nrather unlikely. Our calculated He3(He3,2p)He4 and H3(H3,2n)He4 cross sections\nare in a good general agreement with the experimental data.",
