报告简介：
The symmetry energy at sub- and supra- saturation densities is studied in intermediate energy heavy-ion collisions by using the process of fragmentation. The symmetry energy at sub-saturation density is parameterized by using the (1) National Superconducting Cyclotron Laboratory at Michigan State University, USA (NSCL, MSU) experimental data for the single and double neutrons to protons ratio from free nucleons at incident energy of 50 MeV/nucleon for the Sn isotopes. The new results from neutrons to protons ratio of fragments are also provided. (2) Concept of isospin migration in term of relative difference between the yields of the particles in the overlapping zone to quasi-spectator zone at 50 MeV/nucleon. (3) Multiplicity of neutrons data from the ALADIN 2000 collaboration at GSI, Germany for the projectile spectator fragmentation for the 124 Sn and 124 La projectiles at 600 MeV/nucleon. Apart from this, The compressibilities for the symmetric as well as asymmetric nuclear matter are calculated by comparison with the experimental data of GSI collaboration. The particular sensitive probe among different kind of fragments for the supra-saturation density dependence of symmetry energy is provided. The new coalescence method is developed by applying the additional cut of the binding energy and sensitivity is checked towards the stability of fragments and isospin physics.
