Abstract

Heavy-ion fusion reactions are important and essential to express the dynamical properties of colliding nuclei, and to address the tunneling effect in quantum mechanics. In the fusion process, the ion-ion potential plays an important role in approaching the measured cross section with the experimental value by influencing the tunneling probability of interacting nuclei. In this work, the fusion cross-sections of closed-shell heavy-ion fusion systems have been calculated and analyzed in the framework of coupled channel theory, using the code CCFULL, by fixing the potential depth value = 102.9 MeV and the fusion radius = 1.096 , while, the diffuseness parameter of Wood--Saxon potential is varied from 0.6 to 1.1 to fitting the fusion cross-section data at energies near and below the Coulomb barrier. It was observed that our approach is able to estimating the experimentally observed cross-sections of closed-shell colliding nuclei.
扩散参数对闭壳核聚变截面的影响
在量子力学中,重离子聚变反应对于表达碰撞核的动力学性质和解决隧道效应是至关重要的。在聚变过程中,离子-离子势通过影响相互作用核的隧穿概率,使测量截面与实验值接近。本文在耦合通道理论的框架下,利用CCFULL程序,将势深定为102.9 MeV,聚变半径为1.096,Wood—Saxon势的扩散参数在0.6 ~ 1.1之间变化,计算和分析了闭壳重离子聚变系统的聚变截面,以拟合库仑势垒附近和以下能量处的聚变截面数据。结果表明,我们的方法能够估计实验观察到的闭壳核碰撞截面。
