FUSION AND PERIPHERAL REACTIONS OF C-12+N-14 AT ENERGIES UP TO 13 MEV-A

Angular and energy distributions have been measured for reaction products of the N14 + C12 system at nine bombarding energies in the energy range EN14=34.1 to 178.1 MeV. The fusion and direct reaction components for products from Li to Al have been determined. The experimental fusion cross sections and deduced critical angular momenta are discussed in terms of entrance channel models for compound nucleus formation and the rotating liquid drop model. Hauser-Feshbach calculations of the Z distributions, energies, and angular distributions of evaporation residues are presented and compared to the data. The direct reaction yield has been analyzed with a diffraction model and is also compared with time-dependent Hartree-Fock calculations. The experimental total reaction cross section is in good agreement with optical model calculations.
