弹性散射阈反常和近垒重离子熔合截面增强是低能重离子核反应中的重要现象。已有研究表明,二者是相关的,有理由认为它们有着共同的起源。耦合道理论对一些异常现象的解释获得了极大的成功。为寻求内在的物理因素和更深层次的核反应机制,有必要做进一步的研究。本工作的目的是通 Anomalous elastic scattering threshold and near-heavy ion fusion cross-section enhancement are important phenomena in low energy heavy ion nuclear reaction. Studies have shown that the two are related and that there is reason to believe that they share a common origin. Coupling theory has been extremely successful in explaining some anomalies. In order to seek intrinsic physical factors and deeper nuclear reaction mechanism, further research is necessary. The purpose of this work is to pass
