Michael Hass (The Weizmann Institute of Science, Israel), Low-energy nuclear astrophysics - the fascinating region of A=7

Friday 11 May 2007, 10:00 → 11:00 Europe/Bucharest

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,8B [1, 2] and the 3He, 7Be [3] 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. Of possible astrophysical importance are our recent results regarding the host dependence and temperature dependence of the half life of the electron-capture 7Be radio-nuclide [4]. We also present simulation calculations and plans for experiments with radioactive beams in next-generation facilities. I gratefully acknowledge the fruitful collaboration with colleagues from the Weizmann Institute, Israel, the Soreq Nuclear Research Center, Israel, ISOLDE(CERN), Switzerland and the Paul Scherrer Institute, Switzerland.
