Study of Astrophysical Nuclear Reaction on Beijing Secondary Beam Line GIRAFFE

Abstract: The 11C(p,γ)12N reaction is one of the key processes in hot pp chains.We have carried out a measurement of 11C(d,n)12N reaction.The 11C beam was produced with the secondary beam facility GIRAFFE.The angular distribution was measured and used to deduce ANC through DWBA analysis.We are performinga microscopic study to get the astrophysical S-factor of 11C(p,γ)12N reaction from ANC square constant of 3.5±1.5.This result implies that the direct contribution to (p,γ) reaction is not negligible.
