Abstract
Elastic scattering angular distributions of the weakly bound projectile from have been measured for 11 beam energies ranging from 38 to . Analysis was carried out with the optical model, employing a double folded microscopic real potential with four different density functions. The surface strengths of the interaction potentials were consistent and all exhibited a threshold anomaly. However, the renormalization factor required to obtain an optimum fit to the data varied significantly depending upon which density function was used, cautioning that conclusions about the effect of breakup should not be based solely upon the value of this factor. Fusion cross sections predicted from these potentials were extracted using a barrier penetration model. Comparison with recently published experimental data suggests that the flux removed from complete fusion by breakup is balanced by the flux redirected into the partial fusion channel.
