Description
Summary:Light nuclei were created during big-bang nucleosynthesis (BBN). Standard BBN theory, using rates inferred from accelerator-beam data, cannot explain high levels of <sup>6</sup>Li in low-metallicity stars. Using high energy-density plasmas we measure the T(<sup>3</sup>He,γ)<sup>6</sup>Li reaction rate, a candidate for anomalously high <sup>6</sup>Li production; we find that the rate is too low to explain the observations, and different than values used in common BBN models. As a result, this is the first data directly relevant to BBN, and also the first use of laboratory plasmas, at comparable conditions to astrophysical systems, to address a problem in nuclear astrophysics.
