Abstract
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 within the framework of the modified DWBA. Asymptotic normalization coefficients (ANC's) defining the amplitude of the tails of the N-14 bound-state wave functions in the C-13+p channel are extracted that are in excellent agreement with values found previously with the C-13(N-14,C-13)N-14 reaction. We conclude that C-p1/2(2)=18.2(9) fm(-1) and C-p3/2(2) = 0.91(14) fm(-1) for the virtual decay N-14(g.s.) --> C-13+p. These are necessary for the analysis of the N-14(Be-7, B-8)C-13 and N-14( C-11, N-12) C-13 reactions to extract the ANC's far Be-7+p --> B-8 and C-11+p-->N-12, which determine the direct radiative capture cross sections Be-7(p,gamma)B-8 and C-11(p,gamma)N-12 at astrophysical energies.
