Coupled channel analysis of fusion excitation function for 9Be+64Zn system at near and above barrier energies

Abstract

We have calculated excitation functions of incomplete fusion, complete fusion and total fusion processes for [Formula: see text] system at near and above barrier energies. In particular, breakup effects of weakly bound projectile [Formula: see text], which has been considered as a two body system [Formula: see text] with a breakup threshold of 1.667 MeV, have been studied. The calculations are performed by using the code FRESCO, which is based on Continuum Discretized Coupled Channel (CDCC) approach. The present analysis of the total fusion excitation function for the system [Formula: see text] shows that it is suppressed at above barrier energies and enhanced at sub barrier energies when the breakup effects are taken into account. In addition, the comparison of the probabilities of incomplete fusion from neutron capture and that from alpha capture shows the dominance of former over later.
