高能hA碰撞中的核内级联与靶核碎裂

The Intranuclear Cascade and the Target Fragmentation in High Energy hA Collisions

本文在核内级联效应基础上,提出了一个反映高能强子-核碰撞中靶核碎裂的模型,给出了灰粒子和黑粒子的分布及它们之间的关联。结果表明,核的有限电荷数造成了实验上观察到的靶核碎片分布的饱和性。

A model for describing the target fragmentation in high energy hadron-nucleus collisions on the bases of intranuclear cascade is suggested. The analysis of the correlation between grey and black particles shows that the phenomena of saturation about mean number of grey and/or black particles observed in experiments result from the limitation of charge number in the nu- cleus.
