Asymptotic normalization coefficients for C-13+p -> N-14 Academic Article uri icon


  • The differential cross sections for the reactions Be-9(B-10, B-10)Be-9 and Be-9(B-10,Be-9)B-10 have been measured at an incident energy of 100 MeV. The elastic scattering data have been used to determine the optical model parameters for the Be-9+B-10 system at this energy. These parameters are then used in distorted-wave Born approximation (DWBA) calculations to predict the cross sections of the Be-9(B-10,Be-9)B-10 proton exchange reaction, populating the ground and low-lying states in B-10. By normalizing the theoretical DWBA proton exchange cross sections to the experimental ones, the asymptotic normalization coefficients (ANC's), defining the normalization of the tail of the B-10 bound state wave functions in the two-particle channel Be-9+p, have been found. The ANC for the virtual decay B-10(g.s.)-->Be-9+p will be used in an analysis of the B-10(Be-7,B-8)Be-9 reaction to extract the ANC's for B-8-->Be-7+p. These ANC's determine the normalization of the Be-7(p,gamma)B-8 radiative capture cross section at very low energies, which is crucially important for nuclear astrophysics.
