Abstract Recent resonating group calculations provide a good description of the cross sections for the radiative capture reactions 3He(α, γ)7Be and H(α,γ)7Li. We have reviewed the available experimental data for these reactions and extrapolated them to zero energy by normalizing to the resonating group results in a consistent way; recommended reaction rates as a function of temperature are obtained. From these (α, γ) rates and a survey of other nuclear reactions that influence the production of solar neutrinos, we conclude that remaining uncertainties in the nuclear reaction rates are not a likely explanation of the low observed detection rate in the 37Cl solar neutrino detector. We also find that the reaction rates are sufficiently accurate to predict big bang production of 7Li within ±35% at all relevant densities and to obtain both upper and lower bounds on the universal mass density from the observed 7Li abundance.
