Abstract

The flux of Be7 and B8 neutrinos from the Sun and the production of Li7 via primordial nucleosynthesis depend on the rate of the He3(α,γ)Be7 reaction. In an extension of a previous study showing cross section data at 127-167 keV center-of-mass energy, the present work reports on a measurement of the He3(α,γ)Be7 cross section at 106 keV performed at Italy's Gran Sasso underground laboratory by the activation method. This energy is closer to the solar Gamow energy than ever reached before. The result is σ=0.567±0.029stat±0.016syst nb. The data are compared with previous activation studies at high energy, and a recommended S(0) value for all He3(α,γ)Be7 activation studies, including the present work, is given.
