测量了27Al+27Al耗散反应产物的激发函数，束流27 Al8+的入射能量从114MeV到127MeV变化，能量步长为200keV. 探测角度覆盖了实验室系10°—57°的连续区域. 用不同的理论模型分析了耗散产物的能量自关联函数. 结果表明，反应所形成的中间双核系统的阻尼相干转动造成了激发函数中不可平滑的涨落结构，相干转动的阻尼来自量子混沌运动.

The excitation functions of the dissipative fragments emitted from the reaction of 27　Al+27Al have been measured in the energy region from 114MeV to 127MeV in steps of 200keV. The detection system covered continuous angles from 10° to 57° in laboratory system. The energy autocorrelation functions of the dissipative fragments have been analyzed by using different approaches,especially using the statistical nuclear reaction model with memory. The results indicate that the intermediate dinuclear system formed in the dissipative process is set in a damped coherent nuclear rotation which causes the nonself-averaging oscillation structure in the excitation functions and originates from a typical quantum chaotic motion.
