TL;DR: Evidence of the presence of critical behavior of a finite classical system in the instability region is provided through a study of mass distributions, scaled factorial moments, and anomalous fractal dimensions.
Abstract: We study the behavior of a finite classical system in the instability region. The equation of state of such a system resembles that of nuclear matter. Through a study of mass distributions, scaled factorial moments, and anomalous fractal dimensions, we provide evidence of the presence of critical behavior of our system. Such behavior can be understood by use of the droplet model of the liquid-gas phase transition.

TL;DR: In this paper, a moment analysis in terms of bivariate distributions of global variables for two colliding nuclei at intermediate energy is presented, and it is shown that the selection of the impact parameter through narrow cuts in the total transverse kinetic energy naturally modifies the true fluctuations of the fragment multiplicity distributions.

TL;DR: The multiparticle decay in collisions induced by 44 MeV/nucleon [sup 40]Ar and [sup 132]Xe projectiles on several targets is studied using MEDEA 4[pi] detection system and the impact parameter dependence of the charged particle multiplicity is determined.
Abstract: The multiparticle decay in collisions induced by 44 MeV/nucleon $^{40}\mathrm{Ar}$ and $^{132}\mathrm{Xe}$ projectiles on several targets is studied using MEDEA 4\ensuremath{\pi} detection system. The impact parameter dependence of the charged particle multiplicity is determined. The dependence is strong in peripheral and midcentral collisions and becomes weaker in central collisions. The prediction of a molecular dynamics simulation is in agreement with the experiment.

TL;DR: The Boltzmann-Nordheim-Vlasov (BNV) equation as mentioned in this paper has been extensively used in understanding the dynamics of intermediate energy heavy-ion collisions and provides a good basis for describing the average properties of one-body observables in situations where the fluctuations are small and the effects of correlations are not important.
Abstract: The Boltzmann-Nordheim-Vlasov (BNV) equation 1, also known as the Boltz-mann-Uehling-Uhlenbeck equation, has been extensively used in understanding the dynamics of intermediate energy heavy-ion collisions 2. This kinetic equation provides a good basis for describing the average properties of one-body observables in situations where the fluctuations are small and the effects of correlations are not important. However, when one is interested in processes in which the high-order correlations play a dominant role like, for instance, multifragmentation, such models do not provide a realistic description and are not valid anymore.
