    • Astrophysical S factor for C-13(p,gamma)N-14 and asymptotic normalization coefficients 
      Mukhamedzhanov, AM; Azhari, A.; Burjan, V.; Gagliardi, Carl A.; Kroha, V.; Sattarov, A.; Tang, X.; Trache, L.; Tribble, Robert E. (American Physical Society, 2002)
      We reanalyze the C-13(p,gamma)N-14 radiative capture reaction within the R-matrix approach. The low-energy astrophysical S factor has important contributions from both resonant and onresonant captures. The normalization ...

      We consider the results of two proton transfer reactions, B-10(Be-7, B-8)Be-9 and N-14(Be-7, B-8)C-13, to obtain a weighted average of the measured asymptotic normalization coefficients for the virtual transition 7Be +pB-8. ...

      The N-14(p,gamma)O-15 reaction, which controls energy production in the CNO cycle, has contributions from both resonance and direct captures to the ground and excited states. The overall normalization of the direct captures ...

      The C-13(He-3,d) N-14 proton transfer reaction has been measured at an incident energy of 26.3 MeV. Angular distributions for proton transfer to the ground state and excited states at 2.313 and 3.948 MeV in N-14 are analyzed ...
    • Asymptotic normalization coefficients from the (20)Ne((3)He, d)(21)Na reaction and astrophysical factor for (20)Ne(p,gamma)(21)Na

      The (20)Ne(p,gamma)(21)Na reaction rate at stellar energies is dominated by capture to the ground state through the tail of a subthreshold resonance state at an excitation energy of 2425 keV in (21)Na. Both resonant and ...
    • Determination of the astrophysical S factor for C-11(p,gamma)N-12 from the N-12 -> C-11+p asymptotic normalization coefficient

      The evolution of very low-metallicity, massive stars depends critically on the amount of CNO nuclei that they produce. Alternative paths from the slow 3alpha process to produce CNO seed nuclei could change their fate. The ...
    • Determination of the direct capture contribution for N-13(p,gamma)O-14 from the O-14 -> N-13+p asymptotic normalization coefficient 
      Tang, XD; Azhari, A.; Fu, CB; Gagliardi, Carl A.; Mukhamedzhanov, AM; Pirlepesov, F.; Trache, L.; Tribble, Robert E.; Burjan, V.; Kroha, V.; Carstoiu, F.; Irgaziev, BF. (American Physical Society, 2004)
      N-13(p, gamma)O-14 is one of the key reactions which trigger the onset of the hot CNO cycle. This transition occurs when the proton capture rate on 13N is faster, due to increasing stellar temperature (greater than or equal ...
    • The N-14(Be-7,B-8)C-13 reaction and the Be-7(p,gamma)B-8 S factor
