关于核多体系统的基态关联效应

On Ground State Correlations in NuclearMany-Body Systems

对于一个原子核模型系统在不同耦合强度、不同粒子数情况下的基态关联效应进行了研究，结果表明：当具有稳定的静态形变时，基态关联基本上可用基于静态上的零点振动来解释，因此，关于静态性质的自治场计算是至关重要的。但在开始发生单极形变的临界点附近，它随控制参量的变化显得很复杂、很敏感。看来，在滴线附近的轻核的进一步研究中，关联效应是需要注意考虑的。

The ground state correlation in model systems with different interaction strength and pardcle numbers has been studied. Nunnerical results tell us that if the ground state shape is quite stable, the ground state correlation can be approximately explained by the zero-point vibration based on the stadc ground state. It is rather important to carry out first the static self consistent field calculation. But around the critical point where the monopole deformation begins to occur, behaviors of the ground state conflation become very complicate and sensitive to the variation of controlling parameters. lt seems to indicate that particular attentions should be paid to ground state compilations in further studies of light nuclei near the drip line
