${}^6\mathrm{Li}$ global phenomenological optical model potential

A systematic global phenomenological optical model potential for a ${}^6\mathrm{Li}$ projectile is established by studying the experimental data of elastic-scattering angular distributions and reaction cross sections from ${}^{24}\mathrm{Mg}$ to ${}^{209}\mathrm{Bi}$ below 250 MeV. Based on the obtained ${}^6\mathrm{Li}$ global phenomenological optical model potential, the extensive analysis of ${}^6\mathrm{Li}$ elastic scattering is performed for different targets by comparing with the corresponding experimental data. It is found that the results calculated using the global optical model potential are consistent with a large body of elastic-scattering data for the reactions involving ${}^6\mathrm{Li}$ incidence. Application of the global potential is performed to predict the elastic-scattering angular distributions and reaction cross sections for those targets outside of the mass range. The reasonable results are also obtained.
