| 摘 要： | 研究了基于双核模型的粒子交换势能面.原子核的形变效应对于势能面的形状有较大的影响.在反应过程中,作为反应时间函数的动态形变的变化是显著的.通过求解主方程,对一些基于冷熔合机制的反应道的全熔合几率也进行了讨论. The Potential Energy Surface (PES) for particle exchange in Di nuclear system is studied in detail. It is found that the nuclear deformation effect can change the shape of PES significantly. The dynamical deformation as a function of the reaction time in the reaction process is investigated in a simple model and we found that its variation with time is dramatic. The fusion probabilities P-CN of some reaction channels based on the mechanism of cold fusion are also calculated.

| Abstract: | The Potential Energy Surface (PES) for particle exchange in Di-nuclear system is studiedin detail. It is found that the nuclear deformation effect can change the shape of PES significantly.The dynamical deformation as a function of the reaction time in the reaction process is investigatedin a simple model and we found that its variation with time is dramatic. The fusion probabilitiesPCN of some reaction channels based on the mechanism of cold fusion are also calculated. |
