Isospin dependent multifragmentation of relativistic projectiles
R. Ogul, A. S. Botvina, U. Atav +57
The N/Z dependence of projectile fragmentation at relativistic energies has been studied with the ALADIN forward spectrometer at the GSI Schwerionen Synchrotron (SIS). Stable and r…
Model-independent tracking of criticality signals in nuclear multifragmentation data
J. D. Frankland, A. Chbihi, A. Mignon +41
We look for signals of criticality in multifragment production in heavy-ion collisions using model-independent universal fluctuations theory. The phenomenon is studied as a functio…
Isoscaling and the symmetry energy in spectator fragmentation
W. Trautmann, A. S. Botvina, J. Brzychczyk +5
Isoscaling and its relation to the symmetry energy in the fragmentation of excited residues produced at relativistic energies were studied in two experiments conducted at the GSI l…
Fragmentation in Peripheral Heavy-Ion Collisions: from Neck Emission to Spectator Decays
J. Lukasik, G. Auger, M. L. Begemann-Blaich +40
Invariant cross sections of intermediate mass fragments in peripheral collisions of Au on Au at incident energies between 40 and 150 AMeV have been measured with the 4-pi multi-det…
The ASY-EOS experiment at GSI: investigating the symmetry energy at supra-saturation densities
P. Russotto, M. Chartier, E. De Filippo +89
The elliptic-flow ratio of neutrons with respect to protons in reactions of neutron rich heavy-ions systems at intermediate energies has been proposed as an observable sensitive to…
Tracing a phase transition with fluctuations of the largest fragment size: Statistical multifragmentation models and the ALADIN S254 data
T. Pietrzak, P. Adrich, T. Aumann +54
A phase transition signature associated with cumulants of the largest fragment size distribution has been identified in statistical multifragmentation models and examined in analys…
