^(27)Al+^(27)Al耗散反应中激发函数的测量与统计性质分析

Measurement of Excitation Function and Analysis of StatisticalProperty in ^(27)Al + ^(27)Al mssipative Reaction

通过测量能量从114—120MeV、能量步长为200keV的重离子耗散反应(27)AI＋(27)AI从θ(cm)＝50°-90°的角分布和激发函数，在对所有宏观出射道积分的基础上，分析了重离子耗散反应中激发函数涨落的物理性质．

The angular distribuhon in the range of 0cm = 50-90 and excitationfunchon of the reachon products in heavy ion dissipahve reachon 27Al + 27Al weremeasured, in the incident energy region from 114MeV to 120MeV with 200keV step.The statishcal property of the fluctuation of the excitation funchon in heavy iondissipative reachon was discussed based on the integration of the macro outgoingchannels. conceived 27 March 1998 Supported by the National amural Science Foundation of China (19775057), the Chnese Academy of Seiencesac the Ishtuto theonale di Rsica Nuclears, Laboratori Nationale del Sud Canda- Italy
