| 英文摘要 | In this paper we briefly review the fusion process of very heavy nuclear systems and some theoretical models. We propose a microscopic transport dynamic model, i. e. the Improved Quantum Molecular Dynamic model, for describing fusion reactions of heavy systems, in which the dynamical behavior of the fusion barrier in heavy fusion systems has been studied firstly. We find that with the incident energy decreasing the lowest dynamic barrier is obtained which approaches to the adiabatic static barrier and with increase of the incident energy the dynamic barrier goes up to the diabatic static barrier. We also indicate that how the dynamical fusion barrier is correlated with the development of the configuration of fusion partners along the fusion path. Associating the single-particle potentials obtained at different stages of fusion with the Two Center Shell Model, we can study the time evolution of the single particle states of fusion system in configuration space of single particle orbits along the fusion path. |
