Rapidity distributions of protons from central 197Au+197Au collisions measured by the E895 Collaboration in the energy range from (2-8)A GeV at the Brookhaven AGS are presented. Longitudinal flow parameters derived using a thermal model including collective longitudinal expansion are extracted from these distributions. The results show an approximately linear increase in the longitudinal flow velocity,
给出了布鲁克海文交变梯度同步加速器(AGS)上,能量范围为(2 - 8)A GeV的情况下,E895合作组测量的中心197Au + 197Au碰撞中质子的快度分布。利用包含集体纵向膨胀的热模型从这些分布中提取纵向流参数。结果表明,纵向流速度
