摘要

Lithium isotopes have attracted an intense interest because the abundances of both ~6Li and ~7Li from big bang nucleosynthesis (BBN) are the puzzles in nuclear astrophysics. Many investigations of astrophysical observation 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.
