摘要：

The Li-8(p, d)Li-7 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 E-c.m = 4.0 MeV by using an Li-8 secondary beam. The result of measurement includes the contributions of Li-8(p, d(0))Li-7 and Li-8(p, d(1))Li-7(*). The Li-8(p, d(0))Li-7 component is estimated to be 40%similar to 58% in the mixture angular distribution by analysing the measured result.
