Intermediate Mass Fragments and Isospin Equilibration
Abstract
In heavy ion collisions between projectile and target nuclei having different isospin (N/Z), a transient state of matter with appreciable isospin asymmetry can be created. The measurement of isotopic composition of light clusters (Z = 1, 2) and intermediate mass fragments (IMF) emitted from this transient piece of matter provide an important means of studying isospin equilibration and fractionation in asymmetric nuclear matter. The latter is important for the understanding of the isospin dependence of the nuclear equation of state. In this work, we study the N/Z compostion of the midrapidity region between the projectile and target like fragments, the isotopic composition of fragments at midrapidity and their dependence on the centrality. Further, the neutron enrichment of the light clusters and the issue of isospin equilibration will be presented.
