Abstract

The reaction cross section for the direct radiative proton capture on the the drip line nucleus ¹²N - ¹²N(p,γ)¹³O - was studied at the Cyclotron Institute/Texas A&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^DC _1-12=0.31(5)keVb. Interference between direct and resonant capture leads to a further enhancement of a factor of two.
