It was an aim of this study to clarify the pairing correlation between nucleons in weakly-bound neutron-rich nuclei. The main achievements include: i) I have pointed out that a two-nucleon emission decay of unbound nuclei outside the drip lines strongly reflect the pairing correlation, and thus the dinucleon correlation can be probed by studying the angular correlation of the emitted two nucleons, ii) I have shown that an odd-even staggering of reaction cross sections of neutron-rich nuclei is intimat-ely related to the pairing anti-halo effect, and iii) I have developed a novel model for heavy-ion fusion reactions at energies around the Coulomb barrier, which takes into account the effects of multi-nucleon transfer processes.It was an aim of this study to clarify the pairing correlation between nucleons in weakly-bound neutron-rich nuclei.

这项研究的目的之一是阐明弱束缚丰中子核中核子之间的配对关联。主要成果包括：i)指出非束缚核在滴线外的双核子发射衰变强烈地反映了配对关联，从而可以通过研究发射的两个核子的角关联来探索二核关联；ii)我证明了丰中子核反应截面的奇偶交错与成对反晕效应密切相关；iii)我发展了一个新的库仑势垒附近能量下重离子聚变反应的模型。它考虑了多核子转移过程的影响。这项研究的目的是澄清弱结合丰中子核中核子之间的配对关联。主要成果包括：i)我指出非束缚核在滴线外的双核子发射衰变强烈地反映了配对关联，因此可以通过研究发射的两个核子的角关联来探索双核子关联；ii)我证明了丰中子核反应截面的奇偶交错与成对反晕效应密切相关；iii)我发展了一个新的重离子聚变反应模型，该模型考虑了多核对转移过程的影响。
