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