Effects of unconventional breakup modes on incomplete fusion of weakly bound nuclei

Abstract

The incomplete fusion dynamics of ${}^6$Li + ${}^{209}$Bi collisions at energies above the Coulomb barrier is investigated. The classical dynamical model implemented in the {\sc platypus} code is used to understand and quantify the impact of both ${}^6$Li resonance states and transfer-triggered breakup modes (involving short-lived projectile-like nuclei such as ${}^8$Be and ${}^5$Li) on the formation of incomplete fusion products. Model calculations explain the experimental incomplete-fusion excitation function fairly well, indicating that (i) delayed direct breakup of ${}^6$Li reduces the incomplete fusion cross-sections, and (ii) the neutron-stripping channel practically determines those cross-sections.
