Title: Astrophysical S-factor of the {sup 12}N(p,{gamma}){sup 13}O Reaction Determined from the ({sup 12}N,{sup 13}O) Proton Transfer Reaction

Abstract

The reaction cross section of the radiative proton capture on the drip line nucleus {sup 12}N was studied at the Cyclotron Institute at Texas A and M University. We have employed the indirect Asymptotic Normalization Coefficient method to determine the direct radiative component of the astrophysical S-factor of the {sup 12}N(p,{gamma}){sup 13}O reaction. A value of 0.31(5) keV{center_dot}b was found at zero energy. Interference between direct and resonant captures leads to a further enhancement of a factor of two. The reaction was investigated in relation to the evolution of hydrogen-rich massive objects, Population III stars, because of the role that it may play in the hot pp chain nuclear burning processes occurring in such stars.
