Isospin effects on the energy of vanishing flow in heavy-ion collisions

Abstract

Using the isospin-dependent quantum molecular dynamics model we study the isospin effects on the disappearance of flow for the reactions of ${}^{58}Ni$ + ${}^{58}Ni$ and ${}^{58}Fe$ +${}^{58}Fe$ as a function of impact parameter. We found good agreement between our calculations and experimentally measured energy of vanishing flow at all colliding geometries. Our calculations reproduce the experimental data within 5%(10%) at central (peripheral) geometries.
