Abstract
Excitation functions for the yields of eleven residual nuclei from the $^{14}\mathrm{N}$+ $^{14}\mathrm{N}$ reaction have been measured over the range ${E}_{\mathrm{c}.\mathrm{m}.}=7\ensuremath{-}25$ MeV in steps of \ensuremath{\sim} 250 keV with $\ensuremath{\gamma}$-ray techniques. The magnitude and energy dependence of the excitation functions for the partial yields are very different from those for the $^{12}\mathrm{C}$+ $^{16}\mathrm{O}$ system. The total fusion cross section is similar to that from $^{12}\mathrm{C}$+ $^{16}\mathrm{O}$ 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.NUCLEAR REACTIONS $^{14}\mathrm{N}(^{14}\mathrm{N}, x)$; ${E}_{\mathrm{c}.\mathrm{m}.}=7\ensuremath{-}25$ MeV; measured excitation functions for production of $A=16\ensuremath{-}27$ reaction products, observed small structures at ${E}_{\mathrm{c}.\mathrm{m}.}=15.0, 17.1, 18.5, 20.4, \mathrm{and} 22.0$ MeV; deduced critical angular momentum for fusion.
