/ Abstract
Rapidity distributions of protons from central 197 Au + 197 Au collisions measured by the E895 Collaboration in the energy range from 2 to 8 AGeV 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, h βγ i L , as a function of the logarithm of beam energy.
