Analysis of the $^{16}$O$(d,p)^{17}$O and $^{16}$O$(d,n)^{17}$F transfer reactions to determine astrophysical direct capture cross sections

Abstract

Coupled Reaction Channel Calculations have been performed for transitions to ground and first excited states of 17 F and 17 O at deuteron incident energies from E d =2.279 MeV up to 3.186 MeV. The n+ 16 O and p+ 16 O astrophysical direct capture cross sections have been calculated using the spectroscopic factors obtained from 16 O(d,p) 17 O and 16 O(d,n) 17 F transfer reactions. The astrophysical S-factors are compared to recent experimental data. The Maxwellian-averaged neutron capture cross section at kT=30 keV is obtained as 22(3)µ barn.
