Abstract

Measurements of the fusion cross sections for ${}^{10, 11}B$ + ${}^{12}C$ , ${}^{12}C$ + ${}^{13}C$ , ${}^{12}C$ + ${}^{14}N$ , ${}^{14}N$ + ${}^{14}N$ , and ${}^{14}N$ + ${}^{16}O$ at sub-Coulomb-barrier energies, together with earlier results for ${}^{12}C$ + ${}^{12}C$ , ${}^{12}C$ + ${}^{16}O$ , and ${}^{16}O$ + ${}^{16}O$ , show that the average energy dependence of the fusion cross section can change dramatically with only small variations in the mass and charge of the interacting nuclei.
