“…It is important to note that the total integrated residues cross section in this work is equal to the soft spheres mode1 41 estimate of the total reaction cross section, arguing that we have not "missed" many (or any) fragments. 18 Thus direct comparison of our measured distributions with the firestreak model leads to the conclusion that the model either underestimates the transverse momentlJTl transfer in the collision (or overestimates the longitudinal momentum transfer 3 ). The hydrodynamical model calculation seems to suggest a transverse momentum transfer not observed in our data.…”
