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 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 کاملFusion and Direct Reactions for Strongly and Weakly Bound Projectiles
The interaction of “Li. 9Be and “C projectiles with a “Si target was investigated by measuring the angular distributions of the elastically scattered projectiles and of the emitted protons, deuterons and cc-particles. The experiment was performed in order to deduce direct and compound nucleus process contributions to the total reaction cross section and to study the influence of the projectile ...
متن کاملReaction dynamics for fusion of weakly-bound nuclei
We discuss several open problems of fusion reactions induced by weakly bound nuclei. For this purpose, we solve a one dimensional three-body Hamiltonian with the coupled-channels formalism. We show that the continuum-continuum couplings substantially reduce the total fusion probability at energies above the barrier compared with the no-breakup case, although the fusion probability remains enhan...
