Last Minute from ALADIN: Temperature measurements in Au+Au reactions at relativistic energies

Abstract

We report on temperature measurements of nuclear systems formed in the Au+Au collisions at incident energies of 50, 100, 150, 200 and 1000 A MeV. The target spectator matter was studied at the highest energy and the interacting zone (participants) at the lower ones.The temperature deduced from the isotope ratios was compared with the one deduced via the excited states population. An unexpected disagreement was found between the two measurements.
