Abstract

Dynamical and thermodynamical features of the fragmentation process around the Fermi energy are discussed using data measured at GANIL and GSI facilities with the 4 array INDRA. Presented topics address transport properties and transition phenomena in central and peripheral collisions and give a panorama on the physics of transient systems produced in heavy–ion collisions.

Keywords: Nuclear stopping; scaling laws; fluctuations; heat capacity; fragmentation.

Resumen

Se discuten propiedades dinámicas y termodinámicas del proceso de fragmentación cerca de la energía de Fermi con datos experimentales obtenidos en GANIL y GSI con el arreglo 4 INDRA. Se estudian las propiedades de transporte y fenómenos transitorios in colisiones centrales y periféricas y se presenta un panorama de la física de sistemas transitorios producidos en colisiones de iones pesados.

Descriptores: Frenamiento nuclear; leyes de escala; fluctuaciones; capacidad calorífica; fragmentación.
