大爆炸核合成模型预测的6Li丰度与在前主序星中测得的丰度之间存在差异。为了进一步限制这些恒星中6Li丰度的预测,需要对破坏6Li的反应进行高精度测量。即6Li(p,γ)7Be和6Li(p,α)3He。这些最近在地下核天体物理实验室(LUNA)进行了研究,以测量它们的低能截面。我目前的运动的实验设置和数据分析的现状。
A discrepancy exists between the6Li abundances predicted from big bang nucleosynthesis models and those measured in pre-main sequence stars. To further constrain the predicted abundances of6Li in these stars, high accuracy measurements are required of reactions destroying6Li. Namely6Li(p,γ)7Be and6Li(p,α) 3He. These have recently been studied at the Laboratory for Underground Nuclear Astrophysics (LUNA) to measure their low energy cross sections. I present both the campaign’s experimental setup and current status of the data analysis.
