Optical model parameters for the ^{12}C(^{7}Li,^{7}Li)^{12}C reaction at 63 and 78.7 MeV

Elastic and inelastic scattering of 'Li from "C have been measured at incident energies of 63 and 78.7 MeV. The experimental data were obtained over an angular range from 8„,=8' to 40'. Optical model parameters have been extracted by fitting the elastic scattering data, and deformation lengths have been obtained for the 'Li* (0.48 MeV) state and the "C~ (4.44 MeV) state. No single parameter set was found that fitted the elastic scattering over a wide range of energies via simple changes in the depths of the potentials,
