A large enhancement of the 13C(α,n)16O reaction cross section at low energy limit due to the sub-threshold state in 17O has been predicted, explaining the neutron source of s-process nucleosynthesis. By the 13C(6Li,d)17O transfer reaction, we had deduced the resonance strength of the state. Contrary to the predictions, the sub-threshold state was found to have very small contribution to the astrophysical S factor.
