ABSTRACT Based on an approach recently proposed by us, simultaneous chi2 analyses are performed for elastic scattering, direct reaction (DR), and fusion cross section data for the 6He+209Bi system at near-Coulomb-barrier energies to determine the parameters of the polarization potential consisting of DR and fusion parts. We show that the data are well reproduced by the resultant potential, which satisfies the proper dispersion relation. A discussion is given of the nature of the threshold anomaly seen in the potential.

    ABSTRACT: The energy dependence of the optical potential for the elastic scattering of He on ²°Bi at near and subbarrier energies is studied. Elastic angular distributions and the reaction cross section were simultaneously fitted by performing some modifications in the ECIS code. A phenomenological optical model potential with the Woods-Saxon form was used. There are signatures that the so-called breakup threshold anomaly (BTA) is present in this system having a halo projectile He, as it had been found earlier for systems involving stable weakly bound nuclei.

    ABSTRACT: Fusion radial potential barrier for the 8B + 58Ni system is determined from a simultaneous optical model analysis of elastic scattering angular distributions and fusion data. Besides the nuclear bare potential, dynamical energy-dependent Woods–Saxon polarization potentials, i.e. UF (volume) and UDR (surface), are used. 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 is split into real and imaginary potentials. The detailed physical meaning of these two terms of the optical potential is investigated. The interpretation of the results of our calculations confirms that the proton-halo characteristics of 8B enhance the fusion cross-section.

    ABSTRACT: The energy-dependent real and imaginary parts of the optical potential of some twenty pairs of spin-unsaturated, open j-shell nuclei are calculated in the energy density model, using the complex Skyrme III energy density. The calculated potentials, without any renormalization, reproduce the experimental data on elastic scattering cross sections of all the pairs of nuclei studied. The contribution of the spin density terms, of the Skyrme III energy density, toward such potentials and toward the corresponding elastic scattering cross sections and sub-barrier fusion cross sections are investigated.
