AbstractThe correlation between the elliptic flow nu(2) scaled by the impact parameter b and the shear viscosity eta as well as the specific viscosity eta/s, defined as the ratio of the shear viscosity to the entropy density s, is investigated for the first time in intermediate-energy heavy-ion collisions based on an isospin-dependent quantum molecular dynamic model. The elliptic flow is calculated at balance energies to exclude the geometric influence such as the blocking effect from the spectators. Our study shows that nu(2)/b decreases almost linearly with increasing eta, consistent with that observed in ultrarelativistic heavy-ion collisions. On the other hand, nu(2)/b is found to increase with increasing eta/s.
