Multi-step compound model of heavy-ion fusion

Heavy-ion fusion reactions have been analyzed within a multi-step compound model composed of a dinucleus configuration, coupled to particle and breakup channels as well as to an equilibrated compound nucleus configuration. The resulting fusion cross sections, defined as the summed particle emission cross sections from the equilibrated compound nucleus, are in reasonable agreement with the data for several systems. The resulting angular distributions as well as the time evolution of the system are also discussed.
