Excitation functions for the yields of eleven residual nuclei from the 14N+ 14N reaction have been measured over the range Ec.m.=7-25 MeV in steps of ∼ 250 keV with γ-ray techniques. The magnitude and energy dependence of the excitation functions for the partial yields are very different from those for the 12C+ 16O system. The total fusion cross section is similar to that from 12C+ 16O when compared at the same center of mass energy, but appears to saturate at an energy and magnitude which are lower than expected from previous systematics. Small, regular fluctuations can be seen in the fusion cross section at the 1-2% level.
