10B + 17O fusion cross sections

Abstract

The fusion cross section for 10B + 17O has been measured at four excitation energies in 27Al 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 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 17O + 10B, E(17O)=54, 72, 104, and 124 MeV; measured d2sigmadOmegadE for reaction products from Z=3 to 12. Extracted sigmafusion.
