摘　　要：随着加速器能量的提高,间歇现象的研究在粒子物理学界产生了很大的影响.最初人们对间歇现象的研究主要集中在相对论性产生粒子,很少研究靶核碎裂的间歇行为.近年来,人们发现在高能核核作用中的慢粒子中也存在这种间歇现象.本文对500 AGeV 56Fe-Em作用产生的慢粒子标度阶乘矩分布进行研究,得出500 AMeV 56Fe-AgBr作用靶核蒸发碎片不存在间歇行为.With the increase of the accelerator energy,the research of phenomena of the intermittent had a great impact on particles physics.At first,the study for the phenomenon of the intermittent was focused on the produced relativistic particles,and is few on the intermittent behavior of target nuclear fragmentation.In the recent years,however,the phenomena of the intermittency were found in the slow particles of the interactions of high energy nuclear-nuclear.In this study,the scaled factorial moments of slow particles produced in 56Fe-Em at 500 AMeV have been calculated.It is obtained that non intermittency behavior exists in emission of target evaporated fragments in 56Fe-AgBr Interaction at 500 AMeV.
