Abstract

The ¹³C(α,n)¹⁶O reaction is believed to be the main neutron source reaction for the s-process in AGB stars. The astrophysical S-factors of this reaction have been determined based on an evaluation of the α spectroscopic factor of the 1/2+ subthreshold state in ¹⁷O (Ex = 6.356 MeV) by using the ¹³C(¹¹B,⁷Li)¹⁷O α transfer reaction. Our result confirms that the 1/2+ subthreshold resonance is dominant for the ¹³C(α,n)¹⁶O reaction at low energies of astrophysical interest.
