| Sumario: | Global equilibrium fragmentation inside a freeze-out constraining volume is a working hypothesis widely used in nuclear fragmentation statistical models. In the framework of classical Lennard-Jones molecular dynamics, we study how the relaxation of the fixed volume constraint affects the posterior evolution of microscopic correlations, and how a nonconfined fragmentation scenario is established. A study of the dynamical evolution of the relative kinetic energy fluctuations was also performed. We found that asymptotic measurements of such an observable can be related to the number of decaying channels available to the system at fragmentation time. |
