LI-7-12 AND LI-7+C-13 FUSION REACTIONS AT SUBBARRIER ENERGIES(C)

The Li-7+C-12 and Li-7+C-13 reactions have been studied at incident en ergies below and around the Coulomb barrier, by the measurement of cro ss sections for the characteristic gamma-rays emitted from the residua l nuclei. Statistical model calculations of the decay of the compound nucleus have been used to deduce the absolute cross sections for diffe rent channels and to obtain the total fusion cross sections. There is no evidence for fusion cross section limitations for these systems at energies near the Coulomb barrier as observed in an earlier experiment .
