Pairing correlation and pair transfer reactions of weakly bound nuclei

本研究的目的是阐明弱束缚富中子核中核子之间的配对关系。主要成果包括：i)我指出了滴线外的非束缚核的双核子发射衰变强烈地反映了配对相关性，因此可以通过研究发射的两个核子的角相关性来探索二核子相关性。ii)我证明了富中子核的反应截面的奇偶交错与配对反晕效应密切相关。iii)我开发了一种新的模型，用于在库仑势垒周围能量下的重离子聚变反应，该模型考虑了多核子转移过程的影响。本研究的目的是阐明弱束缚富中子核中核子之间的配对关系。主要成果包括：i)我指出了滴线外的非束缚核的双核子发射衰变强烈地反映了配对相关性，因此可以通过研究发射的两个核子的角相关性来探索二核子相关性。ii)我证明了富中子核的反应截面的奇偶交错与配对反晕效应密切相关。iii)我开发了一种新的模型，用于在库仑势垒周围能量下的重离子聚变反应，该模型考虑了多核子转移过程的影响。

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.
