We discuss results and future plans for low-energy reactions that play an
important role in current nuclear astrophysics research and that happen to
concentrate around the region of A=7. The 7Be(p,gamma)8B and the
3He(4He,gamma)7Be reactions are crucial for understanding the solar-neutrino
oscillations phenomenon and the latter one plays a central role in the issue of
cosmic 7Li abundance and Big-Bang Nucleosynthesis. We also present results
regarding the host dependence of the half life of the electron-capture 7Be
radio-nuclide.
