The reaction cross section for the direct radiative proton capture on the the drip line nucleus {sup 12}N--{sup 12}N(p,{gamma}){sup 13}O--was studied at the Cyclotron Institute/Texas A and M University using the indirect asymptotic normalization coefficient method. This reaction is important in the hot pp chain nuclear burning processes in hydrogen-rich massive objects (Population III stars). The astrophysical S-factor of the direct proton capture was determined at zero energy yielding a value of S{sup DC}{sub 1-12} = 0.31(5) keV b. Interference between direct and resonant capture leads to a further enhancement of a factor of two.
