摘要

通过在接近库仑势垒高度的深亚势垒能量下使用大角度准弹性散射，对包括这些系统在内的重离子反应的核势垒参数进行了具体的系统研究。本理论研究还计算了弹性散射势垒分布 Dqel 与能量的函数关系。单通道（SC）和耦合通道计算是为了得出核势。在与实验数据的比较中，使用了 X2 方差法找出核电势的最佳值。核电势的最佳值是通过单通道计算得出的：16O+166ER , 16O+197Au 分别等于 (60.5, 100) MeV。

A study the 16 O + 166 E R , 16 O + 197 Au Systems Using Calculations of Quasi-elastic Scattering

Specific systematic studies on the nuclear potential parameter for the heavy-ion reactions which includes the systems have been achieved by using large-angle quasi elastic scattering at deep sub-barrier energies close to the Coulomb barrier height. The elastic scattering barrier distribution Dqelas a function of energy has also been calculated in this theoretical study. The single-channel (SC) and coupled-channels calculations have been carried out to elicit the nuclear potential. The chi-square method X2 has been used find the best value of the nuclear potential in comparison with the experimental data. The best values of the nuclear potential were found from the calculations of the single channels for systems: 16O+166ER , 16O+197Au, which are equal to (60.5, 100) MeV, respectively.
