We have calculated excitation functions of incomplete fusion, complete fusion and total fusion processes for system at near and above barrier energies. In particular, breakup effects of weakly bound projectile , which has been considered as a two body system 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 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.

9Be + 64Zn系统在势垒能量以上及以上的融合激发函数的耦合通道分析
我们已经计算出不完全融合,完全融合和完全融合过程的激发函数,用于 系统处于势垒能量以上或以上。特别是弱束缚弹丸的破裂效果,已被视为两体系统 破裂阈值为1.667 MeV。通过使用代码FRESCO来执行计算,该代码基于连续离散耦合通道(CDCC)方法。系统总融合激励函数的当前分析结果表明,当考虑到分解效应时,它在高于势垒能时受到抑制,而在次势垒能处得到增强。另外,对中子俘获和α俘获的不完全融合概率的比较表明,前者占优势。
