Large-space cluster model calculations for the He3(He3,2p)He4 and H3(H3,2n)He4 reactions

摘要

The He3(He3,2p)He4 and H3(H3,2n)He4 reactions are studied in a microscopiccluster model. We search for resonances in the He3+He3 and He4+p+p channelsusing methods that treat the two- and three-body resonance asymptoticscorrectly. Our results show that the existence of a low-energy resonance orvirtual state, which could influence the Be-7 and B-8 solar neutrino fluxes, israther unlikely. Our calculated He3(He3,2p)He4 and H3(H3,2n)He4 cross sectionsare in a good general agreement with the experimental data.
