对3.7AGeV16O束流与核乳胶相互作用所产生的次级α粒子的平均自由程进行了初步测量和分析,并利用另一种统计方法对实验数据进行了计算,没有发现反常现象,
The mean free paths of a projectile fragments produced in 160-Em interactions at 3.7 A GeV have been studied by using a new statistical methods in this paper. It is found there are not any anomalous behaviors in the production of α projectile fragments.
