论文摘要
我们分析了64ni+100MO和28SI+64NI回收的意外深层轰击重型离子融合阻塞的起源。我们的分析基于通过有限元方法实现的改进的耦合通道方法。借助木材 - 撒克逊电势，实验横截面和这些反应的S因子得到了很好的重现。我们发现，耦合矩阵的非对角矩阵元素的说明，传统上在传统的耦合通道方法中忽略了在电位口袋内设置左边界条件的方法，其最小价值对于解释实验数据至关重要。在我们的方法中，我们发现了融合反应12c+12c的S因子的实验数据有很好的一致性，该系统对该系统没有明显的最大值。
We analyse the origin of the unexpected deep sub-barrier heavy-ion fusion hindrance in 64Ni+100Mo and 28Si+64Ni recations. Our analysis is based on the improved coupled-channels approach, implemented by means of the finite element method. With the aid of the Woods-Saxon potential the experimental cross sections and the S-factors of these reactions are remarkably well reproduced. We found that the account on the non-diagonal matrix elements of the coupling matrix, traditionally neglected in the conventional coupled-channels approaches in setting the left boundary conditions inside the potential pocket, and its minimal value are crucially important for the interpretation experimental data. Within our approach we found a good agreement with the experimental data for the S-factor of the fusion reaction 12C+12C, which has no a pronounced maximum for this system.
