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) Phys. Rev. 52(1937)

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

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)
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) 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
