B10 + O17 fusion cross sections

The fusion cross section for B10 + O17 has been measured at four excitation energies in Al27 of E*=48.4, 55.1, 66.9, and 74.4 MeV in order to study possible compound nucleus limitation effects on fusion for light heavy-ion systems at intermediate excitation energies. Comparing this data with other measurements for different entrance channels populating the same compound nucleus it is found that for E*≤60 MeV all fusion bands in the E*-J plane of Al27 appear to be parallel and displaced by the corresponding differences in separation energies, and that for E*>60 MeV the bands tend to converge indicating a possible compound nucleus limitation effect. The data are compared with existing models for entrance channel and statistical yrast line limitations. NUCLEAR REACTIONS O17 + B10, E(O17)=54, 72,104, and 124 MeV; measured d2σdΩdE for reaction products from Z=3 to 12. Extracted σfusion.
