BE-7(P,GAMMA)B-8 CROSS-SECTION AND THE PROPERTIES OF BE-7

We study the nonresonant part of the Be-7(p, gamma)B-8 reaction using a three-cluster resonating group model that is variationally converged and virtually complete in the He-4 + He-3 + 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 Be-7. A range of parameters is found where the most important B-8, Be-7, and Li-7 properties reproduced simultaneously; the corresponding S factor at E(c.m.) = 20 keV is 24.6-26.1 eV b.
