Astrophysical Rate for 12N(p,g)13O Direct Capture Reactions

The proton capture on the unstable nuclei plays a very important role for the nucleonsynthesis. The 12N(p,g)13O reaction rates at the energies of astrophysical interests are estimated with the spectroscopic factor and asymptotic normalization coefficient methods. The present results show that the 12N(p,g)13O reaction may play an important role in x-ray bursts.
