THE <sup>2</sup>H(alpha, gamma)<sup>6</sup>LI REACTION AT LUNA AND BIG BANG NUCLEOSYNTHETIS

THE <sup>2</sup>H(alpha, gamma)<sup>6</sup>LI REACTION AT LUNA AND BIG BANG NUCLEOSYNTHETIS

The <sup>2</sup>H(α, γ)<sup>6</sup>Li reaction is the leading process for the production of <sup>6</sup>Li in standard Big Bang Nucleosynthesis. Recent observations of lithium abundance in metal-poor halo stars suggest that there might be a 6Li plateau, similar to...
