Systematics of carbon- and oxygen-induced fusion on nuclei with 12 < or = A < or = 19
Measurements of the total fusion cross sections for /sup 12/C + /sup 12/C, /sup 13/C, /sup 14/N, /sup 15/N, /sup 16/O, /sup 18/O, and /sup 19/F and /sup 16/O + /sup 16/O have been performed over the energy range from 1.5 to 3 times the Coulomb barrier energy. Fusion barrier parameters were extracted for each system. Three systems, /sup 12/C + /sup 12/C, /sup 12/C + /sup 16/O, and /sup 16/O + /sup 16/O, show rather pronounced oscillatory structure in the energy dependence of the fusion cross sections. The maximum fusion cross sections for the systems studied vary by as much as 10--20%, depending on the particular entrance channel. The specific structure of the interacting nuclei clearly does have an effect; the fusion process is not entirely dominated by the macroscopic features of the ion-ion interaction.
