摘      要：A new global phenomenological optical model potential for the Li7 projectile is derived from the available experimental data of elastic-scattering angular distributions and reaction cross sections from Al27 to Pb208 with incident energies below 200 MeV. It is based on a smooth, unique functional form for the energy dependence of the potential depths, and physically constrained geometry parameters. The elastic-scattering angular distributions and reaction cross sections for other targets are also predicted by the obtained Li7 global phenomenological optical model potential at different incident energies. These results are further compared with the corresponding experimental data. The performance shows that the Li7 global phenomenological optical model potential can give a satisfactory description for Li7 elastic scattering.
