摘要：

The tail of the proton distribution of B-8 determines the rate of the Be-7(p, gamma)B-8 reaction at low energies and is thereby of prime importance for the high-energy solar neutrino flux. We introduce a two-body model for B-8 and analyse different experiments that are sensitive to the tail of the density distribution; most important is the measurement of total interaction nuclear cross-sections. The comparison indicates that the (p, gamma) reaction rate has been overestimated so far.
