| 英文摘要 | The nucleus nucleus interaction potentials for the fusion reactions O-16 + (208)pb, Ni-64 + Ni-64, Ni-58 + Ni-58 and O-16+ Sm-154 are extracted from the improved isospin-dependent quantum molecular dynamics model. The shell correction effects are discussed. The negative shell correction energies lower potential barriers of a certain reaction. The incident energy dependence of the potential barrier is investigated for each system. A complex phenomenon of energy dependence is observed. It is also found that incident energy dependence of the barrier radius and barrier height shows opposite behaviors. The Coulomb potential shows weak energy dependence when distance of two colliding nuclei is lower than the touching distance. The isospin effects of the potential barrier are investigated. The orientation effects of the potential barrier is also discussed for the system O-16+ (154) Sm. The fusion cross sections that correspond to the equatorial orientation of Sm-154 are very low in sub-barrier region because of the high fusion barriers and the shallow potential pockets.
