Study of the primordial Lithium Abundances at CIAE

Abstract

Lithium isotopes have attracted an intense interest because the predicted abundances of both 6Li and 7Li from big bang nucleosynthesis (BBN) do not match experimental observations. Many investigations of astrophysical observations and BBN calculations have been carried out in order to solve the puzzles. Several nuclear reactions involving lithium have been determined at HI-13 tandem accelerator, Beijing, China. The BBN model calculations are then performed to investigate the primordial lithium abundance. The result shows that these nuclear reactions have minimal effect on the primordial abundances of 6Li and 7Li. © Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-ShareAlike Licence.
