摘要：

Elastic and inelastic scattering differential cross sections mere measured in the energy range 30 MeV less than or equal to E-lab less than or equal to 55 MeV for the N-14 + Co-59 system. Ambiguities of the optical potential derived from the analysis of the elastic scattering data were removed by performing calculations at: the radius of sensitivity and by comparison with the available fusion cross section data. A simultaneous analysis of the three mechanisms was performed by coupled channel calculations, and a unique energy independent nuclear potential was found to be able to fit the data. Discussions and comparisons concerning the optical model, the threshold anomaly, full and approximated coupled channel calculations are presented.
