Coupled channels model for radiative capture of nucleons by /sup 12/C. [1 to 10 MeV]
Description
A simple model based upon coupled-channels scattering calculations for nucleons on /sup 12/C was applied to the corresponding radiative capture reactions. It includes only electric dipole transitions via direct capture plus capture occurring via intermediate states consisting of only the 2/sup +/ first excited state of /sup 12/C coupled to a nucleon in the (s,d) shell. It is shown that the shape and magnitude of measured excitation functions of the /sup 12/C(p,..gamma../sub 0/) and /sup 13/C(..gamma..,n/sub 0/) reactions are largely reproduced for excitation energies up to about 10 MeV. Furthermore, it is shown that the excitation functions are strongly affected … continued below

It is shown that the shape and magnitude of measured excitation functions of the /sup 12/C(p,..gamma../sub 0/) and /sup 13/C(..gamma..,n/sub 0/) reactions are largely reproduced for excitation energies up to about 10 MeV. Furthermore, it is shown that the excitation functions are strongly affected by competition and interference between direct capture and the indirect modes. Angular distribution data are also fairly well reproduced by the model. Implications of the success of the model are discussed. 9 figures.
