Subbarrier α transfer reaction 13C(6Li, d) 17O(6.356 MeV, 1/2+) at 3.6 MeV is analyzed with an α + d +13C three-body model, and the asymptotic normalization coecient (ANC) for α+13C → 17O(6.356 MeV, 1/2+), which essentially determines the reaction rate of 13C(α, n)16O, is extracted. Breakup eects of 6Li in the initial channel and those of 17O in the nal channel are investigated with the continuum-discretized coupled-channels method (CDCC). The former is found to have a large back-coupling to the elastic channel, whereas the latter turns out to be signicantly small. The transfer cross section calculated with Born approximation to the transition operator, including breakup states of 6Li, gives (C17O *α13C)2 = 1.03 ± 0.29 fm-1. This result is consistent with the value obtained by the previous DWBA calculation.
