Description
The energy dependence of the optical potential is used to study the threshold anomaly for reactions with the weakly bound projectile 9Be on 144Sm and 64Zn for energies around the Coulomb barrier. The energy dependent potential parameters are obtained from a simultaneous X2-analysis of elastic scattering and fusion data. There are signatures that in fact, the so-called breakup threshold anomaly shows up for these systems. This finding is in agreement with other calculations involving weakly bound projectiles.
