Abstract：
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.
