Nuclear Particle Astrophysics (NPA) Seminar, Michael Hass, Weizmann Institute, “Astrophysical nuclear reactions from Big Bang Nuclear Synthesis to Solar Physics and Solar Neutrinos”

Description
The study of nuclear reactions that are relevant to astrophysical issues plays a central role in the basic understanding of various astrophysical phenomena and of the origin of the elements. In particular, high-precision studies of solar fusion reactions at low energy, using stable nuclear beams, shed light on the energy generation in the Sun, on Solar models and on the issue of solar neutrinos and neutrino oscillations.
In the last 10 years our group has focused on such studies of two central cases, the 4He(3He,g)7Be and the 7Be(p,gamma)8B reactions. The former one also plays a major role in Big-Bang Nucleo-synthesis calculations and in the cosmic 7Li abundance problem. There has been significant progress in this field, resulting in a very good understanding of the relevant reactions, but yet more information is needed and is being produced in order to probe these issues with increased detail and precision.
The talk will summarize the present status of this field and present new results from experiments in Madrid and TRIUMF.
Some points regarding experiments with radioactive beams for issues of “explosive nucleo-synthesis” will also be discussed.
