Based 0n the angular distribution of the 8Li(d,n)9Beg.s. reaction at Ec.m.=8.0 MeV and distorted wave Bo approximation analysis,the single particle spectroscopic factor S1,3/2 for the ground state of 9Be=8Li(×)p is derived to be 0.64±0.21.In addition,we deduce the astrophysical S-factors and rates of the 8Li(p,γ)9Beg.s. direct capture reaction at energies of astrophysical interests.
