New advances for the 3He(4He,γ)7Be solar fusion reaction

We present the current status of the available data and the calculations for the cross section of the 3He(α, γ)7Be reaction — accurate knowledge of which is required for the solar neutrino flux and the primordial 7Li abundance calculations. Precision measurements are being carried out by us in the range of Ecm = 1 to 3 MeV using two types of experimental methods. A brief account of this work is given together with some of the recent theoretical calculations.
