Abstract

We study the nonresonant part of the Be7(p,)8B reaction using a three-cluster resonating group model that is variationally converged and virtually complete in He4+3He+p model space. The importance of using adequate nucleon-nucleon interaction is demonstrated. We find that the low-energy astrophysical S factor is linearly correlated with the quadrupole moment of Be7. A range of parameters is found where the most important B8, Be7, and Li7 properties are reproduced simultaneously; the corresponding S factor at Ec.m.=20 keV is 24.626.1 eV b.
