Determination of the astrophysical S-factor for the $^{12}$N(p,$\gamma )^{13}$O reaction from ($^{12}$N,$^{13}$O) proton transfer reaction

The reaction rate for the radiative proton capture on the drip line nucleus $^{12}$N was determined using the indirect Asymptotic Normalization Coefficient (ANC) method. This reaction is important for studying the nucleosynthesis in Population III stars with low-metallicity. A 23 MeV/nucleon $^{12}$C primary beam from the K500 cyclotron at Texas A{\&}M University was employed. Secondary $^{12}$N beam of 2 $\times $ 10$^{5}$ pps was separated using the recoil spectrometer MARS. The $^{14}$N($^{12}$N,$^{13}$O)$^{13}$C proton transfer reaction at 12 MeV/nucleon was measured to extract the ANC for the virtual decay $^{13}$O-$>^{12}$N + p. The ANC was then used to determine the direct component of the astrophysical S-factor. The results of this measurement will be discussed.
