| 摘 要： | 实验证实,用重离子碰撞合成超重原子核时,准裂变对熔合的抑制是非常重要的.碰撞中双核系统间核子转移所形成的势能面称之为驱动势,它制约核子转移,因而决定熔合与准裂变的竞争.双核系统势能面还提供重离子碰撞合成超重原子核的最佳激发能和最佳弹靶组合的信息. |
| 关 键 词： | 超重核 驱动势 最佳弹靶组合 最佳激发能 |

| Abstract: | The experimental measurements have provided the evidence that the suppression of fusion cross-section caused by quasi-fission is very important for the synthesis of super-heavy nuclei by heavy ion collisions. The potential energy surface due to the nucleon transfer in the collision process is the driven potential, which governs the nucleon transfer, so that governs the competition between the fusion and quasi-fission. The dinuclear system potential energy surface also gives the information about the optimum projectile-target combination, as well as the optimum excitation energy for the synthesis of super-heavy nuclei by heavy ion collisions. |
| Keywords: | super-heavy nucleus driven potential optimum projectile-target combination optimum excitation energy |
