Asymptotic normalization coefficients for14N13C+p from13C(3He,d)14N Academic Article uri icon

abstract

  • The13C(3He,d)14N 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 in14N are analyzed within the framework of the modified DWBA. Asymptotic normalization coefficients (ANC's) defining the amplitude of the tails of the14N bound-state wave functions in the13C + p channel are extracted that are in excellent agreement with values found previously with the13C(14N,13C)14N reaction. We conclude that C2p1/2=18.2(9) fm-1and C2p3/2=0.91(14) fm-1for the virtual decay14N(g.s.)13C+p. These are necessary for the analysis of the14N(7Be,8B)13C and14N(11C,12N)13C reactions to extract the ANC's for7Be+p 8B and11C+p12N, which determine the direct radiative capture cross sections7Be(p,)8B and11C(p,)12N at astrophysical energies.
