AbstractThe ratio of shear viscosity (eta) to entropy density (s) for an equilibrated system is investigated in intermediate-energy heavy-ion collisions below 100A MeV within the framework of the Boltzmann-Uehling-Uhlenbeck model. After the collision system almost reaches a local equilibration, the temperature, pressure and energy density are obtained from the phase-space information and eta/s is calculated using the Green-Kubo formulas. The results show that eta/s decreases with incident energy and tends toward a smaller value around 0.5, which is not so drastically different from the BNL Relativistic Heavy Ion Collider results in the present model.
