Quasi-elastic scattering of C-10,C-11 and B-10 from a Pb-nat target

Angular distributions of the differential cross sections for the quasi-elastic scattering from a Pb-nat target by C-10 at 226 and 256 MeV, by C-11 at 222 MeV and 226 MeV, and by B-10 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
