用~ 8Li放射性束测量了在非均匀模型中对原初核合成有重要意义的~ 8Li（α，n）~（11）B反应的截面。研究的质心能量范围为0.64-2.2 MeV。对所有~（11）B态的散射截面都超过了~ 8Li（α，n）~（11）B（g.s.）在所研究的整个能源区域中至少增加了5倍。
The cross section for the8Li(α, n)11B reaction, of importance to primordial nucleosynthesis in the inhomogeneous models, has been measured using a8Li radioactive beam. The center-of-mass energy range studied was 0.64–2.2 MeV. The cross section to all11B states is found to exceed that for8Li(α, n)11B(g.s.) by a factor of at least five over the entire energy region studied.
