摘要
本文用阶乘矩方法分析了几种入射能量(14.6,60,200 AGeV)下氧、硅和硫离子诱导乳胶核反应和硫离子与金靶相互作用过程的间歇行为。利用EMU01组的实验数据发现,在赝快度间隔1—0.1范围内,这几种核反应过程都有间歇性。间歇指数随入射能量和末态相对论带电粒子平均多重数的增加而减少,随靶核质量的增加而增加。在实验误差范围内,观察到间歇指数随射弹核质量的增加有上升趋势。
The intermittency of multiparticle production processes in high energies oxygen, silicon
and sulphur induced emulsion and sulphur gold interactions are investigated systematically. It
is found that in the pseudorapidity region 1～0.1. the EMU01 data exhabits the intermittent
behaviour. The intermittent indexes are found to decreases with increasing the incident energy
and mean multiplicity and to increase with increasing target mass. It seems also to increase
as the projectile mass increases.
