This work presents an investigation of isospin equilibration in cross-bombarding $^{48,40}$Ca$+^{48,40}$Ca reactions at 35 MeV/nucleon, by comparing experimental data with filtered transport model calculations. In particular, isospin diffusion is studied from the evolution of the isospin transport ratio with centrality. The asymmetry $\delta = (N − Z)/A$ of the quasiprojectile residue is used...
In the framework of heavy ion collisions, isospin transport phenomena can be used as a tool to gather information on the properties of nuclear matter far from equilibrium conditions. The INDRA-FAZIA apparatus, operating in GANIL, is particularly well suited to investigate such kind of phenomena; it exploits the best characteristics of FAZIA (covering the forward polar angles and providing...
The isospin-dependent equation of state of nuclear matter, i.e. symmetry energy $E_{sym}(\rho)$ plays an important role in the study of nuclear physics and Astrophysics. In terrestrial lab, heavy ion collision provides a unique way to constrain $E_{sym}(\rho)$. So a compact spectrometer for heavy ion experiment（CSHINE）is built and coincident events are measured.
Via HBT intensity...
Four different reactions, $^{32}$S+$^{12}$C and $^{20}$Ne+$^{12}$C at 25 and 50 MeV/nucleon, have been measured with the FAZIA detector, isotopically resolving the systems. Events have been well classified and fragment properties have been compared with AMD simulation coupled with the HFl afterburner, dedicated to light nuclei de-excitation. Here we report on a first comparison, shown in C....
The statistical approaches were previously successfully applied
for the description of the disintegration of excited nuclear sources.
Such single sources in equilibrium with the temperature around
6-8 MeV (also with smaller temperatures) can be produced both
from spectator residues in peripheral collisions of nuclei and
after the fusion of nuclei in central collisions at Fermi...
Collisions of heavy ions are the best tools at our disposal to probe nuclear matter. It allows us to reach extreme densities, giving us the possibility to constraint transport models. In particular, at incident energies around 100 MeV/nucleon, a participant zone is formed by a part of projectile and target nuclei.
The aim of this work is to characterize the participant zone. We will focus...
