The 8Li(d,p)9Li reaction and astrophysical 8B(p,γ)9C reaction rate

Angular distribution of the Li8(d,p)Lig.s.9 reaction at Ecm=7.8MeV was measured in inverse kinematics. The square of asymptotic normalization coefficient (ANC) for the virtual decay Li9→Li8+n was derived to be 1.33±0.33fm−1 through distorted wave Born approximation (DWBA) analysis, for the first time. According to charge symmetry, (ANC)2 for C9→B8+p was then extracted to be 1.14±0.29fm−1. We have deduced the astrophysical S-factors and reaction rates for direct capture in B8(p,γ)C9 at energies of astrophysical relevance using the ANC for C9→B8+p extracted from the mirror system.
