In calculating the 7Be(p,7)SB reaction rate, various single particle models have been used to describe the g.s. of 8B. We show that these models produce electric excitation strength distributions that can differ greatly (-30%) from the pioneering model, providing the community with a wide range of v

β¦ Synopsis
Quadrupole couplings for bound states of 7Be are included in describing the capture reaction 7Be(p,y)8B. We verify, contrary to what we had initially stated (Nucl. Phys. A 615 (1997) 69), that the energy behaviour of the Astrophysical S-factor in the energy range of interest is not significantly sensitive to the core couplings in the g.s. of 8B, although its overall magnitude is shifted.
