本文用双重折叠方法计算了两个任意取向形变核之间的核相互作用和库仑相互作用。采用简化的Skryme型相互作用。在描述重离子聚变反应的驱动势中，考虑了原子核形变和取向引起的原子核相互作用和库仑相互作用的贡献。到目前为止，还没有一个令人满意的理论来描述重离子聚变过程中核的动态形变和取向的演化。我们的研究结果估计了上述影响的大小。
A double-folding method is used to calculate the nuclear and Coulomb interaction between two deformed nuclei with arbitrary orientations. A simplified Skryme-type interaction is adopted. The contributions of the nuclear and Coulomb interactions due to the deformation and orientation of the nuclei are evaluated for the driving potential used in the description of heavy-ion fusion reaction. So far there is no satisfactory theory to describe the evolution of the dynamical nuclear deformation and orientations during the heavy-ion fusion process. Our results estimate the magnitude of the above effects.
