“…These values agree with each other to within 3% and give an estimate of the critical temperature of bulk nuclear matter as T c = 17.9 ± 0.4 MeV. This value agrees well with theoretical predictions [38][39][40][41][42].…”

Abstract. The finite size of nuclei and the Coulomb interaction make it difficult to describe systems interacting through the strong force into thermodynamic terms. Our task is to extract the phase diagram of the theoretical infinite symmetrical uncharged nuclear matter from experiments of nuclear collisions where the systems are neither infinite, symmetrical, nor uncharged. Decay yields from such experiments are translated into coexistence densities and pressures by use of Fisher's droplet model. This method is tested on model systems such as the Ising model and a system of particles interacting via the LennardJones potential. The specific problems inherent to nuclear reactions are considered. These include finite size effects, Coulomb repulsion, and the lack of a physical vapor in contact with a decaying system. Experimental data of compound nucleus experiments are studied within this framework, which is also shown to extend to higher energy reactions. Finally, the phase diagram of nuclear matter is extracted.

“…Moreover as the system is then located in the mechanically unstable spinodal region of the phase diagram, additional information can be found in searching for characterization of the dynamics of the phase transition, which in nuclei may proceed through nucleation or spinodal decomposition. Many theoretical predictions being in favour of the latter [5], a third signal of phase transition might be the evidence of spinodal decomposition.…”

Finite systems such as atomic nuclei present at phase transition specific features different from those observed at the thermodynamic limit. Several characteristic signals were found in samples of events resulting from heavy ion collisions at and above the Fermi energy. The concomitant observation of different signatures of a liquid-gas phase transition in nuclei on a given sample strongly supports the occurrence of this transition.

We introduce isospin dependence in the cluster recognition algorithms used in the Quantum Molecular Dynamics model to describe fragment formation in heavy ion collisions. This change reduces the yields of emitted nucleons and enhances the yields of fragments, especially heavier fragments. The enhancement of neutron-rich lighter fragments mainly occurs at mid-rapidity.Consequently, isospin dependent observables, such as isotope distributions, yield ratios of n/p, t/ 3 He, and isoscaling parameters are affected. We also investigate how equilibration in heavy ion collisions is affected by this change.
