Isospin dependence of collective flow in heavy-ion collisions at intermediate energies. Academic Article uri icon

abstract

  • Within the framework of an isospin-dependent Boltzmann-Uehling-Uhlenbeck model using initial proton and neutron densities calculated from the nonlinear relativistic mean-field theory, we compare the strength of transverse collective flow in reactions 48Ca+58 Fe and 48Cr+58 Ni, which have the same mass number but different neutron/proton ratios. The neutron-rich system (48Ca+58 Fe) is found to show significantly stronger negative deflection and consequently has a higher balance energy, especially in peripheral collisions. 1996 The American Physical Society.
