Potential Energy Surface and Fusion Probability in DNS Model

Keywords： super heavy element , potential energy surface , fusion probability

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 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.
