Recent solar neutrino experiments have shown that both $\phi(^8$B) and the neutrino flux ratio $\phi(^7$Be)/$\phi(^8$B) are substantially below their standard solar model values, leading some to discount the possibility of an astrophysical…

The 7Be(p,gamma)8B reaction is one of the major source of uncertainties in estimating the 8B solar neutrino flux and is critical for undertsanding the Solar Neutrino Problem and neutrinos. The main source of uncertainty is the existence of…

It is shown that future solar neutrino experiments (SNO, Super-Kamiokande and others), in which high energy neutrinos will be detected (mostly from 8B decay), may allow to answer in a model independent way the question whether there are…
