Thermodynamic Variables from Spectator Decay
W. Trautmann, ALADIN collaboration
New results for the masses, excitation energies, temperatures, and densities of excited spectator systems at breakup are presented. They were obtained in two recent experiments wit…
New Temperature Measurements in 197Au + 197Au Collisions
W. Trautmann, ALADIN collaboration
We report on new measurements of breakup temperatures for target spectators from 197Au + 197Au reactions at 1000 MeV per nucleon. The temperatures rise with decreasing impact param…
Source Temperatures and Sizes in Central Collisions
C. Schwarz, ALADIN collaboration
For midrapidity fragments from central 50-200 AMeV Au+Au collisions temperatures from double ratios of isotopic yields were compared with temperatures from particle unbound states.…
Determination of Critical Exponents in Nuclear Systems
W. F. J. Mueller, ALADIN collaboration
Signatures of critical behaviour in nuclear fragmentation are often based on arguments from percolation theory. We demonstrate with general thermodynamic considerations and studies…
