摘　　要：In this paper,xve have studied the properties of eigenfunctions in a three-level Lipkin model whose classical counterpart can exhibit classical chaos.In the regime of classical chaotic motions,sensitivity of eigenfunctions to parameter perturbation is exposed,which may be taken as a quantum signature of classical chaos.

关 键 词：chaos. Lipkin CHAOS
