单核子在具有八极以上形变的平均势场中发现有混沌运动．通过研究系统非定态波函数的时间演化特征，而使研究量子混沌与研究经典混沌的思路更趋一致，特别是能体现量子状态对初始条件的敏感性。给出了当初态选为二维不对称谐振子动力学对称条件下的、满足坐标动量最小测不准关系的相干态时，八极形变耦合作用下量子状态正则变量的期望值及测不准度随时间演化的理论表示．
The mononuclear nuclei find chaos in the average potential field with octopole deformation. By studying the temporal evolution of the unsteady wave function of the system, the idea of studying quantum chaos and classical chaos is more consistent, especially the sensitivity of the quantum state to the initial conditions. The expectation values and uncertainty of quantum state regular variables under the coupling of octupole deformable are given when the coherent states which satisfy the minimum uncertainty of coordinate momentum under the condition of symmetric dynamics of two dimensional asymmetric oscillator Theoretical representation of evolution over time.
