Astrophysical S‐factor of the 12N(p,γ)13O Reaction Determined from the (12N,13O) Proton Transfer Reaction Conference Paper uri icon

abstract

  • The reaction cross section of the radiative proton capture on the drip line nucleus 12 N was studied at the Cyclotron Institute at Texas A&M University. We have employed the indirect Asymptotic Normalization Coefficient method to determine the direct radiative component of the astrophysical S-factor of the 12 N(p,γ) 13 O reaction. A value of 0.31(5) keVb 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. © 2008 American Institute of Physics.
