摘要
对3.7AGeV16O-Em作用产生的慢粒子标度阶乘矩分布进行研究,得出间歇指数随矩阶数的增加而增加,随靶核质量的增加而减小:反常分形维数随q的增加而增加:对于每一个q值,dq随平均多重数的增加而减小,表明在3.7AGeV16O-Em作用中多粒子产生具有自相似级联的性质.
The scaled factorial moments of slow particles produced in ^16O-Em at 3.7AGeV have been calculated. It is obtained that the intermittency exponent increases with increasing moment order and decreases with increasing target mass, the anomalous fractal dimension dq decreases with increasing multiplicity for each order of the moment. This behavior of anomalous dimensions dq reveals a self-similar cascade mechanism in the case of the interactions of ^16O-Em at 3.7AGeV.
