  4. Clustering Structure • 自上世纪30年代以来，原子核内部结构被广泛探索。结团结构在很早就被人提出。原子核结团结构研究在实验和理论两个方面都取得了一定得突破。 Phys. Rev. 52(1937) 1083-1106 Phys. Rev. 52(1937) 1107- 1122

  5. Clustering Structure • Possible Clustering formations: line Chain, Octuple, triangle, ring-like, flower like. M. Freer, et al. Phys. Rep. 432(2006) 43-113

  6. Clustering Structure • 反对称分子动力学模型Anti-symmetrized Molecular Dynamics (AMD) • 反对称分子动力学模型AMD模型运用了自旋宇称投影和电磁特性的方法来分析解释，从而得到了核内显著的结团结构。 Introduction

  7. Clustering Structure Density distribution of matter, protons, and neutrons of the intrinsic states with the AMD model in states of 10Be. The ρstands for intrinsic matter densities. Introduction

  8. Clustering Structure • 分子轨道模型Molecular Orbital (MO) • 分子轨道模型(MO)对轻核采用分析其宇称带的方法，从而得到了显著的结团结构。 • Prog. of Theo. Phys. 65(1981) 204 Introduction

  9. Clustering Structure The α-α dependence of the 0+ states with MO model in 10Be. There appear three 0+ states in the low-lying energy region. The solid line shows the state which has an overlap with the Φ(1/2+,-1/2+) configuration dominantly. Introduction

  10. Clustering Structure • Fermion Molecular Dynamics (FMD) • Nucl. Phys. A 752(2005) 321-324 Introduction

  11. Clustering Structure • Generator Cluster Model (GCM) Introduction

  12. Clustering Structure • Effective Liquid Drop Model (ELDM) Introduction

  13. Clustering Structure • Generalized Density-Dependent Cluster Model (GDDCM) Introduction
