用反对称分子动力学的微观方法系统地研究了光不稳定核Li、Be、B和C的结构。该理论方法对于研究覆盖不稳定核的各种核的基态和激发态是非常有用的。计算成功地再现了许多核结构的实验数据：能量、半径、磁偶极矩、电四极矩、跃迁强度。理论结果表明，不稳定核中可能出现各种奇异现象，如类分子结构、中子皮、大变形等。我们研究了结构随中子数和激发能的增加而发生的变化，发现类壳层结构和团簇结构之间有很大的变化。讨论了不稳定核聚集发展的机制。
Structures of light unstable nuclei, Li, Be, B and C isotopes are systematically studied with a microscopic method of antisymmetrized molecular dynamics. The theoretical method is found to be very useful to study ground and excited states of various nuclei covering unstable nuclei. The calculations succeed to reproduce many experimental data for nuclear structures; energies, radii, magnetic dipole moments, electric quadrupole moments, transition strength. In the theoretical results it is found that various exotic phenomena in unstable nuclei such as molecular-like structures, neutron skin, and large deformations may appear in unstable nuclei. We investigate the structure change with the increase of neutron number and the excitation energies, and find the drastic changes between shell-model-like structures and clustering structures. The mechanism of clustering developments in unstable nuclei is discussed.
