摘 要: | 13N(p, γ)14O is is one of the key reactions in the hot CNO cycle which occurs at stellar temperatures around T9≤0.1. At the energies of astrophysical interest, the 13N(p, γ)14O reaction is dominated by the low energy tail of the s-wave capture on the broad 1- resonance at Er = 527.9 keV (which has a total width of (37.34-0.9) keV). A considerable effort has been expended in recent years to determine the parameters for the resonance. These include the direct measurements using the radioactive ^13N beam, particle transfer reactions, and coulomb dissociation of high-energy ^14O beams in the field of a heavy nucleus.
