Optical potentials for the elastic scattering ofLi6+C12,Li6+O16, andLi7+C12

New elastic scattering angular distributions extending over the large angular range 10°—170° c.m. are reported for ${}_{}{}^6{}_{}{}^{}\mathrm{Li}$+${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$ at 24 and 30 MeV, ${}_{}{}^6{}_{}{}^{}\mathrm{Li}$+${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$ at 25.7 MeV, and ${}_{}{}^7{}_{}{}^{}\mathrm{Li}$+${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$ at 34 MeV. These data have been analyzed and are well described by the optical model using Woods-Saxon potentials, or by potentials with a double-folded real part. Using these and previously published data, average energy-dependent potentials have been obtained. Improved descriptions of the elastic scattering of ${}_{}{}^6{}_{}{}^{}\mathrm{Li}$+${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$, ${}_{}{}^6{}_{}{}^{}\mathrm{Li}$+${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$, and ${}_{}{}^7{}_{}{}^{}\mathrm{Li}$+${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$ for energies from the Coulomb barrier up to 26 MeV/nucleon are obtained with these new average potentials compared with existing ones.
