Title: Astrophysical S-factors for the p+16O and n+16O captures from the analysis of 16O(d,n)17F and 16O(d,p)17O transfer reactions

Abstract

Coupled reaction channels calculations were performed for the 16O(d,n)17F and 16O(d,p)17O transfer reactions for the ground and first excited states at several energies from Elab=2.29 MeV up to 3.27 MeV. A strong polarization effect between the entrance channel and the transfer, 16O(d,n)17F (1/2+,0.495) and 16O(d,n)17O (1/2+0.87), channels was observed. This polarization effect had to be taken into account to all orders for obtaining realistic spectroscopic factors from these reactions. The 16O(p,{gamma})17F and 16O(n,{gamma})17O direct captures were calculated using the Asymptotic Normalization Coefficients (ANC) values from these transfer reactions analysis. The astrophysical S-factors were compared to measurements. The Maxwellian-averaged neutron capture cross section at kT=30 keV was 22(3){mu}barn.
