Abstract

A comprehensive study on the coupling strength was conducted using the barrier distribution derived from fusion and quasi-elastic measurements. A brief overview of the extraction of the quasi-elastic scattering barrier distribution is provided by presenting quasi-elastic measurements conducted for the ¹⁶O+¹⁶⁵Ho system. A model-independent technique was used to examine data from various systems published in the literature to relate the different observables obtained from the barrier distribution. The systematic analysis shows the collective behavior of the interacting ions and correlates the structure with the barrier distribution. A comparison of the experimentally determined cumulative coupling strengths for various systems (different projectiles on the same target) revealed that, in addition to the Coulomb factor Z_PZ_T is significant. The barrier distribution proved to be a suitable tool for investigating the structural characteristics of interacting ions.

重离子反应中耦合效应的系统研究

利用融合和准弹性测量得到的势垒分布对耦合强度进行了全面的研究。通过对16O+165Ho体系进行的准弹性测量，简要介绍了准弹性散射势垒分布的提取方法。一种与模型无关的技术被用于检查来自文献中发表的各种系统的数据，以关联从屏障分布中获得的不同观测值。系统分析显示了相互作用离子的集体行为，并将结构与势垒分布联系起来。对不同系统（不同弹丸在同一目标上）的累积耦合强度进行了比较，结果表明，除了库仑因子外，ZPZT也是显著的。势垒分布被证明是研究相互作用离子结构特征的合适工具。
