Global phenomenological optical model potential for the Li7 projectile nucleus

A new global phenomenological optical model potential for the $^{7}\mathrm{Li}$ projectile is derived from the available experimental data of elastic-scattering angular distributions and reaction cross sections from $^{27}\mathrm{Al}$ to $^{208}\mathrm{Pb}$ 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 $^{7}\mathrm{Li}$ global phenomenological optical model potential at different incident energies. These results are further compared with the corresponding experimental data. The performance shows that the $^{7}\mathrm{Li}$ global phenomenological optical model potential can give a satisfactory description for $^{7}\mathrm{Li}$ elastic scattering.
