Determination of the astrophysical S factor for 11C(p,gamma)12N from the 12N->11C+p asymptotic normalization coefficient.

Original language description

The evolution of very low-metallicity, massive stars depends critically on the amount of CNO nuclei that they produce. Alternative paths from the slow 3 alpha process to produce CNO seed nuclei could change their fate. The 11C(p,gamma)12N reaction is animportant branch point in one such alternative path. At energies appropriate to stellar evolution of very low-metallicity, massive stars, nonresonant capture dominates the reaction rate. We have determined the astrophysical S factor for the 11C(p,gamma)12N reaction using the asymptotic normalization coefficient for 12N->11C1+p to fix the nonresonant capture rate. In our experiment, a 110 MeV 11C radioactive beam was used to study the 14N(11C, 12N)13C peripheral transfer reaction and the asymptotic normalization coefficient.
