Coulomb breakup effects on the optical potentials of weakly bound nuclei

Abstract

The optical potential of halo and weakly bound nuclei has a long range part due to the coupling to breakup that damps the elastic scattering angular distributions. In order to describe correctly the breakup channel in the case of scattering on a heavy target, core recoil effects have to be taken into account. We show here that core recoil and nuclear breakup of the valence nucleon can be consistently taken into account. A microscopic absorptive potential is obtained within a semiclassical approach and its characteristics can be understood in terms of the properties of the halo wave function and of the reaction mechanism. Results for the case of medium to high energy reactions are presented.

      Nuclei in this region of the chart may be relevant to the r-process, and thus of importance for studies using Coulomb breakup. Following the first calculations on pygmy resonances based on two- and three-body models, it was soon realized that the role of the continuum and of the nuclear contribution was crucial to explain the experimental data on the EM response obtained in breakup experiments [295,297,300,303,304,330–340]. Calculations based on effective field theories started to appear recently [341].

      In this work, the core recoil effect was taken into account. The findings of Ref. [134] concerning the steeper slope of the fusion excitation functions of several heavy-ion systems at deep sub-barrier energies prompted several authors [145–149] to critically assess the adequacy of the optical potential that describes the elastic scattering data in accounting for the fusion ones as well. In Ref. [146], 21 heavy-ion (HI) systems were analyzed using the standard double-folding optical potential (DFOP) with the M3Y effective interaction.
