A theoretical approach is developed to study systematically the influence of the nuclear surface tension coefficient, γ , of the proximity formalism on the isotopic behavior of the fusion dynamics over a wide range of neutron-rich colliding systems with condition of1 ≤ N / Z < 1.6 for their compound nuclei. Here six different versions of the surface energy coefficient ( γ -PD03, γ -MS67, γ -MS66, γ -MN81-I, γ -MN81-II and γ -MN76) in the calculation of the nuclear potential based on the original proximity potential 1977are employed. It is found that the fusion barrier characteristics and fusion cross sections follow a linear isotopic dependence which is sensitive to the change in the nuclear surface tension between the reacting nuclei. The maximum sensitivity of the data to this technical parameter is obtained for the use of the γ -PD03 version. Further, it is shown that the sensitivity of the isotopic behavior of th...

核表面张力系数在富中子碰撞核聚变动力学同位素依赖性中的作用：聚变势垒的新参数化

发展了一种理论方法来系统地研究在1≤N / Z <1.6的条件下，宽范围的中子富集碰撞系统中，核表面张力系数γ对邻近形式主义对聚变动力学同位素行为的影响为其复合核。在此，根据原始接近度计算核势时，有六个不同版本的表面能系数（γ-PD03，γ-MS67，γ-MS66，γ-MN81-I，γ-MN81-II和γ-MN76）潜在的1977被雇用。发现聚变势垒特性和聚变截面遵循线性同位素依赖性，其对反应核之间的核表面张力的变化敏感。使用γ-PD03版本可获得该技术参数的最大数据敏感性。
