Abstract
The elastic and inelastic cross sections of Li6 on Si28 at 240 MeV, and quasielastic cross section of Li7 and Li11 on Si28 at 177.8 and 319 MeV, respectively, are analyzed with the coupled-channels method. The collective nuclear level density is used to determine the deformation parameter regarding to the first-excited state of Si28. The results are in agreement with the experimental data and indicate the need of using a nuclear structure model such as nuclear level density to reduce the ambiguity between the optical model parameters and the deformation parameter. Additionally, the spin-orbit potential is found to have an important role in reproducing the data of the quasielastic scattering of Li7 and Li11 on a Si28 target. © 2015 American Physical Society.
