We study the exotic structure of nuclei near the drip-line by using a core plus valence nucleons model. The sudden change of the radius of oxygen isotopes at 230 is investigated in a model space of the core plus valence nucleons. The key mechanism to make such the change comes from change of the dominant contribution of channels in the core nucleus induced by the presence of the valence nucleons.

本文用实加价核子模型研究了滴线附近核的奇异结构。在核加价核子模型空间中研究了氧同位素半径在230处的突变。造成这种变化的主要机制是价核子的存在引起的芯核中通道的主导贡献的变化。
