Quasi-elastic scattering of C10,11 and B10 from a Pbnat target

Angular distributions of the differential cross sections for the quasi-elastic scattering from a Pbnat target by C10 at 226 and 256 MeV, by C11 at 222 MeV and 226 MeV, and by B10 at 173 MeV were measured at the Heavy Ion Research Facility in Lanzhou, Radioactive Ion Beam Line in Lanzhou (HIRFL-RIBLL). Contributions from the inelastic scattering channels to these data are found to be negligibly small with coupled-channel calculations within the angular range covered by this experiment. These data can be well reproduced by optical model calculations with systematic nucleus-nucleus potentials. The reduced total reaction cross sections were compared with other existing data.
