Influence of density dependent symmetry energy on Elliptical flow

The effect of density dependent symmetry energy on elliptical flow is studied using isospin-dependent quantum molecular dynamics model(IQMD). We have used the reduced isospin- dependent cross-section with hard(H) equation of state to study the sensitivity of elliptical flow towards symmetry energy in the energy range of 50 - 1000 MeV/nucleon. The elliptical flow becomes zero at a particular energy termed as transition energy. A systematic effort has been made to pin down the transition energy for the density dependent symmetry energy

The study of multifragmentation around transition energy in intermediate energy heavy-ion collisions

Fragmentation of light charged particles is studied for various systems at different incident energies between 50 and 1000 MeV/nucleon. We analyze fragment production at incident energies above, below and at transition energies using the isospin dependent quantum molecular dynamics(IQMD) model. The trends observed for the fragment production and rapidity distributions depend upon the incident energy, size of the fragments, composite mass of the reacting system as well as on the impact parameter of the reaction. The free nucleons and light charged particles show continous homogeneous changes irrespective of the transition energies indicating that there is no relation between the transition energy and production of the free as well as light charged particles

Thermalization and temperature reached in heavy-ion collision using the isospin-dependent quantum molecular dynamics model

We study the nuclear dynamics involved in heavy-ion collisions using the isospin-dependent quantum molecular dynamics (IQMD) model. In particular, the density and temperature reached in heavy-ion collision has been studied for the various forms of density-dependent symmetry energy. The density and temperature of nuclear matter increase with the stiffness of symmetry energy. Our findings conclude the nuclear stopping as an effective probe for the temperature reached in heavy-ion collisions

Effect of the density dependent symmetry energy on fragmentation

The effect of the density dependence of symmetry energy on fragmentation is studied using isospin-dependent quantum molecular dynamics model(IQMD) Model. We have used the reduced isospin-dependent cross-section with soft equation of state to explain the experimental findings for the system 79_Au^197 + 79_Au^197 for the full colliding geometry. In addition to that we have tried to study the collective response of the momentum dependent interactions(MDI) and symmetry energy towards the multifragmentationComment: Accepted for Oral Presentation in Rutherford Centennial Conference 8-10 Aug, 2011, University of Manchester, U
