计算了核对称轴不同相对取向时的熔合位垒.基于双核模型观念,考虑了熔合与准裂变的竞争,通过数值法求解主方程,计算了76Ge+208Pb,48Ca+244Pu核对称轴不同相对取向对熔合概率的影响,探索了最有利于超重元素合成的弹靶相对取向.取向不同时,对熔合反应的影响较大,计算结果表明弹靶碰撞为腰对腰时,更有利于发生熔合反应. Based on the concept of binuclear model, the competition between fusion and quasi-fission was considered, and the main equation was solved numerically. The relative orientation of the symmetry axis of 76Ge + 208Pb and 48Ca + 244Pu nuclei was calculated. On the probability of fusion and explores the relative orientation of the projectile that is most conducive to the synthesis of super-heavy elements.When the orientations are different, the impact on the fusion reaction is large, and the calculation results show that the fusion reaction is more favorable when the projectile collision is waist-to-waist .
