B10+O17fusion cross sections

The fusion cross section for ${}_{}{}^{10}{}_{}{}^{}\mathrm{B}$ + ${}_{}{}^{17}{}_{}{}^{}\mathrm{O}$ has been measured at four excitation energies in ${}_{}{}^{27}{}_{}{}^{}\mathrm{Al}$ of $E^{*}=48.4, 55.1, 66.9, \mathrm{and} 74.4$ 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 $E^{*}\le 60$ MeV all fusion bands in the $E^{*}-J$ plane of ${}_{}{}^{27}{}_{}{}^{}\mathrm{Al}$ appear to be parallel and displaced by the corresponding differences in separation energies, and that for $E^{*}>60\mathrm{}$ 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.
