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.

这项研究的目的是阐明弱构成的富含中子的核中核子之间的配对相关性。主要成就包括：i）我指出的是，滴水线外的未结束核的两核发射衰变强烈反映了配对相关性，因此可以通过研究发射的两个核的角度相关的角度相关，ii）i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i is of奇特的反相式的反相，成分的成分 - 成分的成分 - 抗Halo效应和III）我已经开发了一个新型模型，用于在库仑屏障周围的能量上进行重离子融合反应，这考虑了多核子转移过程的影响。这是本研究的目的，旨在阐明弱结合的富含中子核的核子中核子之间的配对相关性。主要成就包括：i）我指出的是，滴水线外的未结束核的两核发射衰变强烈反映了配对相关性，因此可以通过研究发射的两个核的角度相关的角度相关，ii）i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i is of奇特的反相式的反相，成分的成分 - 成分的成分 - 抗Halo效应，以及III）我已经开发了一种新型模型，用于在库仑屏障周围的能量上进行重离子融合反应，这考虑了多核子转移过程的影响。
