Collective dynamics of weakly bound neutrons studied with nuclear density functional theory

利用核密度泛函理论，研究了含小结合能中子的富中子核中的集体动力学。我们已经阐明了对振动模和与之相关的中子对转移幅度的反常行为。我们发展了一个连续的准粒子随机位相近似，用于描述与r过程核合成相关的直接中子俘获截面。阐明了近滴线原子核中双中子关联的微观机制。

Using the nuclear density functional theory, we have studied collective dynamics which emerge in neutron-rich nuclei containing neutrons with small binding energy. We have clarified anomalous behaviors of the pair vibrational mode and associated neutron-pair transfer amplitude. We have developed a continuum quasiparticle random phase approximation designed to describe the direct neutron capture cross section relevant to the r-process nucleosynthesis. We have clarified the microscopic mechanism of the di-neutron correlation in near-drip-line nuclei.
