N2 - The astrophysical factor of 8B(p,γ)9C at zero energy, S 18(0), is determined from three-body model analysis of 9C breakup processes. The elastic breakup reaction 208Pb(9C,p8B)208Pb at 65 MeV/nucleon and the one-proton removal reaction of 9C at 285 MeV/nucleon on C and Al targets are calculated with the continuum-discretized coupled-channels method (CDCC) and the eikonal reaction theory (ERT), respectively. The asymptotic normalization coefficient (ANC) of 9C in the p-8B configuration, Cp8B9C, extracted from the two reactions shows good consistency, unlike in previous studies. As a result of the present analysis, S18(0)=66±10eVb is obtained.
