Cross-section measurement of 7Be+d and its implications in the Big Bang Nucleosynthesis.

ORAL

Abstract

The cross sections of nuclear reaction 7Be+d, which is a possible path of destruction of mass-7 nuclides in Big-Bang nucleosynthesis, were measured at center-of-mass energies between 0.2 MeV and 1.5 MeV. The experiment was performed with the ANASEN active-target detector system at the RESOLUT facility of Florida State University. We measured cross sections consistent with prior measurements at higher energies but significantly higher at lower energy, especially in the Gamow window. The implications of these cross-sections in the primordial lithium abundance will be discussed.
