Abstract: | The angular distributions and energy spectra of 11B, 10B, and 9Be fragments of 12C in the angular range from 1.0° to 7.5° at 100 MeV/u were obtained via 12C + 12C scattering. Detailed comparisons are presented between the experimental data and the modified antisymmetrized molecular dynamics (AMD-FM), binary intranuclear cascade model (BIC) and Liège intranuclear cascade model (INCL++). The experimental angular distributions and energy spectra are well reproduced by the AMD-FM calculations but fail to be reproduced by the physical models installed in the Geant4 program, including the BIC and INCL++ models. |
