Influence of projectile breakup on fusion reactions induced by Be-9 at near barrier energies

摘要

We have analyzed the fusion excitation functions of various fusion reactions involving Be-9 as projectile in the near barrier energy region using proximity potential and quantum diffusion approach. In particular, the role of breakup is investigated in these fusion reactions. For Be-9 + Sn-124, Tm-169, Ta-181, Re-187 projectile-target combinations an overall suppression in fusion cross section is observed while for Be-9+ Sm-144, W-186, Pb-208, Bi-209 systems overall enhancement is found in near barrier energy region. The agreement between data and predictions is found to be improved significantly when breakup effects are properly accounted for. (C) 2018 Elsevier B.V. All rights reserved.
