摘要
本文基于相对论重离子碰撞的参加者几何模型,用唯象参数引入次级碰撞效应,较好地符合了NA35及WA80组的多重数与横能的快度分布数据。结果表明在几何模型基础上恰当考虑次级碰撞等非几何因素的重要性。
Based on the geometrical participant-model in RHIC the effect of secondary collisions is
considered by introducing a phenomenological parameter. The rapidity distributions of E_T
and n of NA 35 and WA80 groups are fitted very well. The result shows that it is very impo-
rtant to include non-geometrical effects, such as secondary collisions on the basis of geometr-
ical models.
