通过在形成超重核的重离子俘获和熔合过程中引入位垒分布函数的方法对双核模型做了进一步发展．超重核形成过程中的俘获、熔合和蒸发3个阶段分别采用了半经验的耦合道模型、数值求解主方程和统计蒸发模型的方法来描述．计算了近年来Dubna小组利用热熔合反应48Ca(243Am,3n-5n) 288-286115和48Ca(248Cm,3n-5n)293-291116合成超重新核素的蒸发余核激发函数．系统分析了48Ca轰击锕系元素U,Np,Pu,Am,Cm合成超重核Z=112-116产生截面的同位素依赖性．给出了合成超重新核素最佳的弹靶组合和入射能量,即有最大的超重核产生截面．计算说明,壳修正能和中子分离能是影响超重核生成截面产生同位素依赖性的主要因素．
The binuclear model is further developed by introducing the barrier distribution function during the heavy ion trapping and fusion of the super heavy nuclei. The three stages of trapping, fusing and evaporation in the process of super-heavy nucleus formation are described by semi-empirical coupled-channel model, numerical solution of main equation and statistical evaporation model respectively. In recent years, the Dubna subgroups have been used to calculate the EKF of the superheavy nuclides by the thermal fusion reaction of 48Ca (243Am, 3n-5n) 288-286115 and 48Ca (248Cm, 3n-5n) 293-291116. The isotope dependence of the cross section of Z = 112-116 in the synthesis of actinides U, Np, Pu, Am and Cm by 48 Ca bombardment was systematically analyzed. The optimal combination of target and target energy for synthesis of super-heavy neutron is given, that is, the largest cross-section of super-heavy nuclei is generated. The calculation shows that the shell correction and the neutron separation can influence the isotope dependency of the superheavy nuclei.
