Fusion suppression and sub-barrier breakup of weakly bound nuclei.
The mechanism for the large suppression of complete fusion in the 9Be+208Pb reaction has been investigated through measurement of sub-barrier breakup of 9Be. Excluding breakup through the 8Be ground state, whose lifetime is too long, a prompt breakup component remains, having sufficient probability to explain the observed suppression of complete fusion. This appears to be associated with intera...
متن کاملTransfer and breakup of light weakly-bound nuclei
We investigate the origin of the effects observed in the fusion cross section of light weakly bound nuclei, through a review of the most recent experimental and theoretical works. In particular we focus on the well-documented fusion suppression at energies just above the potential barrier. We show that, besides the couplings to the breakup process, effects due to the couplings to transfer need ...
متن کاملEnhanced excitation of Giant Pairing Vibrations in heavy-ion reactions induced by weakly-bound projectiles
The use of radioactive ion beams is shown to offer the possibility to study collective pairing states at high excitation energy, which are not usually accessible with stable projectiles because of large energy mismatch. In the case of two-neutron stripping reactions induced by He, we predict a population of the Giant Pairing Vibration in Pb or Sn with cross sections of the order of a millibarn,...
متن کاملRelating breakup and incomplete fusion of weakly bound nuclei through a classical trajectory model with stochastic breakup.
A classical dynamical model that treats breakup stochastically is presented for low energy reactions of weakly bound nuclei. The three-dimensional model allows a consistent calculation of breakup, incomplete, and complete fusion cross sections. The model is assessed by comparing the breakup observables with continuum discretized coupled-channel quantum mechanical predictions, which are found to...
متن کاملUnderstanding the interplay between sub–barrier breakup of Li and above-barrier suppression of complete fusion
With the discovery of halo nuclei, and recent intensive development of radioactive ion beams (RIBs) around the world, there is renewed interest in studying interaction of weakly-bound light nuclei as a basis for understanding interactions of halo nuclei and RIBs. Using a novel experimental approach [1], reactions of the weakly–bound nuclei Be and Li with heavy targets consistently showed suppre...
