粒子-振动模型对原子核^9Be的应用

Particle-vibration model-application to nucleus ~9Be

利用粒子—振动模型,研究原子核9Be的基态特性和低激发态,把9Be看作是以8Be为核心的振动与核心外另一中子的耦合.结果表明,理论计算与实验结果符合很好;原子核9Be的基态是核心8Be的表面集体振动与单粒子运动耦合的结果.

The structure of nucleus ~9Be is investigated in terms of Particle-Vibraton Model.The nucleus is considered as a two-body system composed of core and one outside neutrons in Particle-Vibraton Model.The structure of nucleus ~9Be is investigated in terms of Particle-Vibraton Model.The low-lying states and the ground state of ~9Be are calculated,and the results are in good agreement with experiments.The conclusion shows that the nucleus ~9Be was caused by coupling of single particle motion with collective vibration of cove ~8Be.
