耦合道(CC)效应是自然界的一个普遍现象,在近库仑势垒能区重离子核反应中起重要作用。第一个静态形变耦合道效应是Stokstad等对16O+ASm体系熔合反应的系统研究中发现的。后来,Heinning等发现了转移总强度与熔合截面增强的联系。在具有多个正Q值中子转移道(PQNT)的32S+96Zr体系中也观察到了大的熔合截面增强。但另一种对熔合截面增强的可能解释是靶核96Zr具有强的八极振动态。为判断是八极振动态还是正Q值中子转移导致的熔合截面增强,选择具有相似正
Coupling Channel (CC) effect is a common phenomenon in nature and plays an important role in heavy ion nuclear reaction near the energy region of Coulomb barrier. The first static deformation coupling effect was found by Stokstad et al. In a systematic study of the fusion reaction of the 16O + ASm system. Later, Heinning et al. Found that the total transfer strength and fusion cross-section enhancement. Large fusion cross section enhancement was also observed in the 32S + 96Zr system with multiple positive Q value neutron transfer paths (PQNTs). However, another possible explanation for the enhancement of the fusion cross-section is that the target nucleus 96Zr has a strong octupole vibration. In order to determine whether the octahedral vibrational or positive Q-value neutron transfer leads to the enhancement of the fusion cross section,
