摘要
在 =193 GeV 的 UU 碰撞中，测量了前向快度区 的 产生不变产额，作为碰撞中心度的函数。给出了不变产额和核修正因子 ，并与相同快度区间的 AuAu 碰撞结果进行了比较。此外，给出了相同中心度类别下 UU 与 AuAu 碰撞不变产额的直接比值，并用于研究 聚合的作用。在 Glauber 计算中使用了变形 Woods-Saxon 分布的两种不同参数化形式来确定每个中心度类别的核子-核子碰撞数 ，发现这两种参数化给出的 值显著不同。给出了使用两种变形 Woods-Saxon 分布所得 值的结果。测得的比值表明，对于外围和中等中心碰撞， 相对于二元碰撞标度的压低在 UU 和 AuAu 中是相似的，但对于最中心的 UU 碰撞， 显示出较小的压低。结果与如下图像一致：对于中心碰撞，由 聚合导致的 产额增加变得比由能量密度增加导致的产额减少更为重要。对于中等中心碰撞，关于 聚合与压低之间平衡的结论取决于使用哪种变形 Woods-Saxon 分布来确定 。
