Spatial barrier distributions for 8B+58Ni from a simultaneous optical model analysis of elastic scattering and fusion data, A. Gomez Camacho, Instituto Nacional de Investigaciones Nucleares, Mexico − Fusion and total reaction spatial barrier distributions for 8B+58Ni at several bombarding energies around the Coulomb barrier, are determined from a simultaneous optical model analysis of elastic scattering and fusion data.  Besides the nuclear bare potential VN, energy dependent optical Woods-Saxon polarization potentials, UF (volume) and UDR (surface) are assumed.  That is, UF is a potential that accounts for polarization effects emerging from couplings to the fusion channel and UDR for effects due to direct reaction absorption couplings.  Each of these potentials UF and UDR are in turn, split into real and imaginary potentials VF, WF and VDR and WDR respectively, which are related via the dispersion relation.  The potentials parameters of all of these potentials are determined from a simultaneous fit to elastic scattering and fusion cross section data.  In this work, the position and height of the fusion and total reaction potential barriers are calculated from the sum of the Coulomb (Vcoul), bare (VN) and the determined energy dependent real polarization potentials (VF and VDR).  It is found that the position and height of the barriers agree with those obtained from a Wong fitting for the fusion and total reaction data.
