Understanding fusion and its suppression for the 9Be projectile with different targets

The role of the breakup process and one-neutron stripping on the near barrier fusion are investigated for the weakly bound projectile Be-9 on Si-28, Y-89, Sn-124, Sm-144, and Pb-208 targets. Continuum-discretized coupled channels (CDCC) calculations for the breakup with a Be-8 + n model of the Be-9 nucleus and coupled-reactions channel (CRC) calculations for the one-neutron stripping to several single-particle states in the target are performed for these systems. A good description of the experimental fusion cross sections above the Coulomb barrier is obtained from the CDCC-CRC calculations for all the systems. The calculated incomplete fusion probabilities for different target systems are found to be consistent with the systematic behavior of the complete fusion suppression factors as a function of target atomic mass, obtained from the experimental data.
