Аннотация
The 3 He(, ) 7 Be and 3 H(, ) 7 Li astrophysical S factors are calculated within the no-core shell model with continuum using a renormalized chiral nucleon-nucleon interaction. The 3 He(, ) 7 Be astrophysical S factors agree reasonably well with the experimental data while the 3 H(, ) 7 Li ones are overestimated. The seven-nucleon bound and resonance states and the + 3 He/ 3 H elastic scattering are also studied and compared with experiment. The low-lying resonance properties are rather well reproduced by our approach. At low energies, the s-wave phase shift, which is non-resonant, is overestimated.
