Mass asymmetry dependence of elliptical flow at intermediate energy

Abstract

The present work deals with the theoretical study of the elliptical flow for mass asymmetric collisions by means of Isospin-dependent Quantum Molecular Dynamical (IQMD) model. The work focuses on the study of sensitivity of elliptical flow towards Coulomb potential and symmetry energy for mid-rapidity region at energy 50 MeV/nucleon by using soft equation of state. Our results show that Coulomb interaction potential dominates the reaction dynamics over symmetry energy. Elliptical flow is strongly affected by the mass asymmetry of the colliding nuclei.
