Measurement of Angular Distribution for the ⁸Li(p,d)⁷Li Reaction

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 E_c.m.=4.0MeV 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.
