Pairing correlation and pair transfer reactions of weakly bound nuclei

点击翻译按钮获取中文摘要

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.
