Abstract：
The structure properties of Li isotopes are investigated in the framework of large-basis shell model.0hω calculation can reproduce the structure of ^6,7Li, but for some states of ^8,9Li far from β-stability line the effect of(0+2)hω excitation should be taken into account for reproducing the experiment at data.For drip line nuclei,enlarging model space or changing the interaction can not reproduce the exotic properties of nucleus ¹¹Li.The exotic properties of some states of nuclei ^6—8Li are also briefly discussed.
