Abstract

Cluster aspects of the nuclear structure manifest themselves in, among many other types of nuclear reactions, the breakup reactions of weakly-bound nuclei and their couplings with the other reaction channels. In the present work we analyzed the breakup coupling effects to the elastic scattering angular distributions of \(^{11}\)Be with a \(^{208}\)Pb target at an incident energy of 140 MeV. Weighted mean local polarization potentials (WMLPPs), which mimic the dynamic polarization potentials (DPPs) induced by the breakup coupling effects to the elastic scattering channel, were obtained from continuum discretized coupled channel (CDCC) calculations. Suppression of the Coulomb-nuclear interference peaks (CNIPs) of the elastic scattering angular distributions is found to be caused by the destructive interference between the Coulomb and the Coulomb-distorted nuclear amplitude due to the WMLPPs. Comparisons between the WMLPPs and the theoretically calculated Coulomb dipole polarization potentials (CDPPs) suggest that the breakup coupling effect of the \(^{11}\)Be+\(^{208}\)Pb system cannot be represented by the CDPPs alone.
