8Li（p，d）7 Li反应在非均匀大爆炸核合成和r过程的种子核产生阶段起着重要作用。这是第一次，它的角分布在向后的角度进行了测量，在逆运动学在EC. m。= 4.0 MeV，通过使用8Li次级束。测量结果包括8Li（p，d 0）7 Li和8Li（p，d1）7 Li * 的贡献。通过对测量结果的分析，估计8Li（p，d 0）7 Li组分在混合角分布中占40%~58%。
The 8Li(p, d)7Li reaction plays an important role in the inhomogeneous Big Bang nucleosynthesis and in the seed-nuclide production phase for the r-process. For the first time, its angular distribution at backward angles was measured in inverse kinematics at Ec.m. = 4.0 MeV by using an 8Li secondary beam. The result of measurement includes the contributions of 8Li(p, d0)7Li and 8Li(p, d1)7Li*. The 8Li(p, d0)7Li component is estimated to be 40%~58% in the mixture angular distribution by analysing the measured result.
